Makes no sense.


Who is that  "he"  who suddenly appears in the post ?

If you are so careless about what you post to the forum,  why I should take care about it   ?   ?    ?     ?      ?

Suppose you travel north at 15 kilometers per hour for 2 hours then travel east. If at one place cross%28he%29 cross%28is%29 you are 34 kilometers from your starting point, how many hours have you traveled?

The statement of the problem is deficient -- it must specify that the speed going east is the same as the speed going north. In order to solve the problem, we must assume that is the case.

A diagram of the problem will show you going 30 kilometers north (2 hours at 15km/h), then traveling east for some distance, ending 34 kilometers from your starting point.

That makes a right triangle with one leg 30 and hypotenuse 34. Use the Pythagorean Theorem to find the length of the other leg.

Then use that length and the speed of 15km/h to find the amount of time spent traveling east.

Then add that to the 2 hours you spent traveling north to find the total time traveled.
