Where does it say you only have 2 hour? You can average 60 mph for 10 hours right? There is no reason why you can not drive faster for 1 more hour and have an average of 60mph. Maybe I am reading it wrong.



ur not reading it wrong ur just not getting it

the town is 60 km away and for 1 hour you travel 30 kph so ur halfway. the only way to get sixty would be to travel for another hour at 90 kph but if u did that you would 60 miles past the town and if u slow don then the average speed would be less then 60 so it is impossible

Now hold on a sec! Who said you had to go straight there?? There is only one road in your town?

Besides which, what if you want to measure the mode average instead of the mean Then it doesn't matter how long you drive or at what speed as long as you spend more time at 60hm/hr then at any other one given speed.

Simple explanation: Basically, it is asking how you can get there in an hour. average 60 kph with a distance of 60 km = an hour of travel time. You travel 30 km in an HOUR. It is now too late to make up time. The hour is over. Hopefully, that clears up confusion.

You know what the problem is... No where in the question does it say that you have only 1 hour to complete the task. People are missing the fact that "figuring that out" is the main part of the answer. You know you only have 1 hour because it says "YOU TRAVELED HALF WAY" Half way of 60 is 30 and you are traveling at 30 PER HOUR, so if your total distance at that point is 30kh it MUST HAVE TAKEN 1 hour to do it. Now that your HOUR is used up, Even if you traveled at 4 billion miles an hour, you can not change the fact that your Hourly Rate of Travel "WAS" 30Km per hour.... s***, Now I'm confusing myself... My head hurts. . . . . . I need a drink.lol

I'm sorry, you'll have to read the question again. It doesn't ask how you can get there in an hour, it asks how you can get there traveling at an average of 60km/hr. And the answer is you make your trip longer. It's only impossible for those with small imaginations.

Now, perhaps it was meant as a trick question, in which case the question will have to be reworded to put a time limit, or to exclude the possibility of extending your trip.

to sum it up here are the possibilities:

1) Instantaneously warp from current point (time = 1h, distance traveled = 30km) to destination
2) Continue to your destination but reverse time to the point where your averages becomes 60 km/h
3) Detour to lengthen travel time to average out to 60 km/h

number 3 being most reasonable

Precisely! Humbug to impossible!

THATS FUNNY. REDICULOUS AT BEST. "WARP" lol,,, "While your at it, just hook up a Flux-Capacitor" to your forehead and run 88 MPH Backwards, and maybe you can GO BACK IN TIME and just travel 60 the entire trip" Clowns....

Form the original question:

how fast do I have to go for the rest of the way


aesculapius' answer:

2) Continue to your destination but reverse time to the point where your averages becomes 60 km/h

Sorry you didn't answer the question "How fast?" in any of your possibilities. You are adding too many variables and hypotheticals, so just accept the original solution. This problem was supposed to get you to make wrong assumptions in averaging speeds and it obviously worked on some people.

the answer i proposed was just an extension of the original solution involving time and space relativity. "warping" isn't good terminology to use but what i mean't was just break from current location to final instantaneously and warp kind of implies that, but isn't exactly a good word to use. i never said the no solution was incorrect under current real-life circumstances
