Hello all

First post here

Obviously we can agree that there are multiple answers.

I had to post because the past 11 pages made me laugh.

My personal opinion is 48, but I see the logic of 12, 24, 15.5 and even 9.6.

Thanks for making me laugh all.

And TEX, PLEASE, PLEASE come tell us what you meant with this!!!

the total length is 6/6 = 72'
1/2 or 3/6 is in the ground
1/3 or 2/6 is in the water
3/6 + 2/6 = 5/6 - 6/6 = 1/6
So therefore 1/6 = 12' out of the water, the total length, so 6 x 12' = 72'

**But what makes you assume that it is 1/3 of the entire pole? The problem states: "One half of the pole is in the ground, another one third is covered by water and eight feet is out of the water."

Another- would imply 'in addition to' or 'along with' So why would one assume that this reffering to a fraction of the entirety?

Please correct me if im wrong!

Whenever fractions are used, there is an implicit "of the" following the ratio being discussed.
"One half of the pole is in the ground, another one third of the ______ is covered by water and eight feet is out of the water."

What makes more sense to go in the blank based on common English?
A.) pole
B.) portion of the pole which is not in the ground

Let's insert each and see which one looks more correct:
A.) "One half of the pole is in the ground, another one third of the pole is covered by water and eight feet is out of the water."

B.) "One half of the pole is in the ground, another one third of the portion of the pole which is not in the ground is covered by water and eight feet is out of the water."

In this case, the word "another" implies that they are talking about the same thing i.e. the whole pole.
If they changed the object to be something else, they wouldn't use the word "another" there.
