Simple example, if the journey is 30 miles, then the first half of the distance (15 miles) will have taken an hour at 15mph. You need to cover the full 30 miles in that hour to average 30mph, so you need to teleport from there to the finish ...[text shortened]... ed x time: X = 30 (T + U) = 30T + 30 U
To summarise X = 30T and X = 30T + 30U. Hence U = 0.
Correct. I can only hope that this was the first time you heard this problem and didn't seek help, its really cool to figure it out yourself.
Now changing gears a bit, name the 8 letter word with only one vowel. Then, name the word with three sets of double letters in a row (I actually knew this second one, thanks to Encylclopedia Brown).

I hadn't seen it before, but I do have a degree in mathematics. Probably I should have left it for someone who has had less mathematical training - sorry, I just couldn't resist.

8 letter word: rhythmic
Don't know the other one.
One for Londoners: name the tube station whose name contains none of the letters of the word "mackerel".

Originally posted by abejnood A truck travels 15 mph for the first half of the distance of a trip. How fast must it travel in the second half of the distance in order to average 30 mph for the total trip?
Poorly worded. If the first and second half of the trip is measured in distance, then the answer is trivial. So the fact is this is a simple algebra problem, the infinite answer doesn't wash. You guys are just joking i hope. 😉

If the answer is trivial, you should have no problem showing it to us. 😉

Yes it is so obvious isn't it? Your cautions are indeed justified, i was trying to nail down a working definition for intelligent and intelligent behavior.
