Pole in lake

While English isn't my first language (Bad English is:) I think some are reading too much into the "another". There can't really be another third because we haven't established a first third. Perhaps an effort to reword the problem for clarity. (I hope you don't mind, TEX.)

You are right, but we have established a fist 1/2 of the same item. To reword the problem you would have to remove another; then it fits and I would agree with the 48 answer.

Something like...

There is a pole in a lake. One half of the pole is in the ground, one third is covered by water and eight feet is out of the water. What is the total length of the pole in feet?

simply removing the word another does wonders for the question; makes it a simple math problem actually so logically another has importance.

If you assumed that the 1/3 is considering only the part that is NOT in the ground you would receive a different answer, but the problem does not say that.

We assume one thing you assume another, the word speaks for itself. But it does, by using the word another it requires you to consider "another" of something.

There is a pole in a lake. One half of the pole is in the ground, another one third is covered by water and eight feet is out of the water. What is the total length of the pole in feet?

another 1/3 covered by water, now depending on if you view 'another' as...

adj ~

1 : different or distinct from the one first considered

~ Another 1/3 of the remaining half

2 : some other

~ we can obviously ignore this meaning as it has no relevance

3 : being one more in addition to one or more of the same kind

~ Here is where it might be on your side, but an example of another in this context would be something on the lines of <have another piece of pie> so another of something of the same kind not another part of something already accounted for. So we could argue (us 24ers) that this enforces our side of the debate.

or

pron ~

1 : an additional one of the same kind : one more

~ Although I do not agree with the relevance of this, one could argue that it would be in addition to what is already known so it 'could' fit as 1/3 of the total length.

2 : one that is different from the first or present one

~ One that is different from the first (1/2) eg 1/3 of the second 1/2

3 : one of a group of unspecified or indefinite things <in one way or another>

~ no relevance

So given the definition of another in almost any context goes with a stronger argument for the answer to be 24 (which is what I believe it to be).

To say we presume that 'another' dictates the remaining half cannot be said without calling your own presumption that it is regarding 1/3 of the total length, to define it sides with us (that believe it to be 24).

12ft.

8 feet are in the ground, those 8 feet are also out of (not in) the water, because they are in the ground. So if the other 1/3 is in the water, then the total length is 12ft.

But if one is to say that the 1/2 in the ground accounts as part of the 8ft not in the water, one could argue that the ground under the lake would be wet as well (because it would be) so the 1/3 of it in the water would account for the half in the ground as well and it would spin this off into la~la land. :huh:

Oops, I missed the part about 1/2 being in the ground. Let me clarify

12ft

6ft (1/2) in the ground (it may be wet but it is not in the water)

4ft (1/3) in the water.

2ft is the rest of the poll sticking out from the surface. (totaling 8ft not in the water)

-12ft total

But the ground under the lake has water in it and the pole that is in the ground in the lake under the water.... is in the water.

Under that pretext.

Under that pretext.

Just about any ground has water in it unless it's dry rock.

Hmm, what if the lake is under ground?

I don't get why everybody is doing fractions and percentages... It's really simple math.

First you start out with the 8 feet you know of, then you multiply it by 3 (because 1/3 is in the water so you do the inverse) to get 24.

After that you just multiply it by 2 because of the 1/2 in the ground to get 48.

half the pole is in the ground 1/2 =3/6

1/3 the pole is in the water 1/3=2/6

8ft of the pole is above the water

1=6/6

6/6 - 3/6 - 2/6 = 1/6

8ft = 1/6 of the pole

8ft x 6 = 48ft

the pole is 48ft long

I still say the ground is not water... It could be 12ft.

im new and this one caught my eye for some weird reason....

real quick explanation:

turn the fractions into percentages

1/2 = 50%

1/3 = 33%

50% + 33% = 83%

17% of the pole is above water

8 / .17 = 47.058823529411764705882352941176

just depends on what value you are gonna round to

I agree with the 12ft. answer.

The wording is strange and makes you think why not just say '8 feet are in the air' if in the air is what you meant? Really, only because 'in the air' is not what is meant. What IS meant is that 8ft is not in the water, exactly as stated. If not in the water, where can it be? In the ground, or in the air. So we know:

3/6 = in ground

2/6 = in air

4/6 = 8 feet

So the entire pole = 12 feet.

"WORD" "PROBLEMS" require skill sets as both grammartician and mathematician. [with a little [un]common sense thrown in.] :)

The answer is 48feet. If you have a different answer, check one of the above skill sets. In the spirit of this website, should we rewrite the OP's to suit obscure interpretations? The "and" preceeding the 8 feet connects this phrase to the "another" following the comma, therefore the 8 feet is not part of the original 50% in the ground. [so common sense and grammar win out over obscure interpretation.] This one is a word problem, not so much a trick question which would beg for effort to look for hidden clues. ;)

Chuck Norris swam out into the water and removed the pole, and with his mighty strength he roundhouse kicked the pole into outerspace. Hence removing the issue of how much is sticking where.

im probally wrong and im okay with that but my guess is 16 feet because 8 feet of pole is out of water and half of the pole is in the ground which technically is not under water so the lenghth of pole in the ground is 8 feet doubled to equal the whole pole is 16. maybe. i think i should have done something with the 1/3 being in the water so my calculations are incomplete oh well

There is a pole in a lake. One half of the pole is in the ground, another one third is covered by water and eight feet is out of the water. What is the total length of the pole in feet?

Spoiler for Just a guess from me on how to solve it.:

1/3+1/2=8

1/3=2/6

1/2=3/6

2/6+3/6=5/6=8

so I think the answer will

be whatever 1/3 of 8 is

plus 8

I got 32.242424242424242424242424242424

Anyhow that's what I got but that was just a guess from what I remember but I do remember you having to change the bottom numbers to work with fractions that were different like the 1/2 and 1/3 by finding a closest number that they both went into.

Definitely a 48 ft pole.

With the length of the pole as "P" then... P divided by 2 for the portion in the ground + P divided by 3 for the portion in the water + 8 for the final bit out of the water. This then looks something like P = P/2 + P/3 + 8 then solve the equation, you get 48.

I believe that the pole is only 12 feet long.

HELLO...

1/2 is under the ground, which LEAVES 1/2 of the pole.

1/3 is under the water but above the ground. This means that 2/3 of the remaining half is taken away.

This leaves 1/3 of that half.

1/3 of one half is 1/6. This is the portion of the pole that is both above ground AND above water.

If 1/6 of the pole is 8 feet long, so the whole pole must be 48 feet long.

Are people allowing for the inverse universe trapezoid destabilisation of axis of N,S (North/South pole). There are some sub aquations to be considered for the water and root canal work at the spring equinox according to the Gregorian calendar. Further, the ground is subject to tremor and hippy hippy shake siZeMick activity and given that a piece of wood may change it's volume by 6.8% growth in water and 7.7% shrinkage in natural regular drying conditions not to mention the decay that has taken place since the original OP.
