Physics homework..?

Question

A plane flies 22km north in 0.25h. It then proceeds south for 35km which take it 0.2h. What is the average velocity of the plane?

Answer 1

What sort of wanker asks the same question twice? Boy, you must be galactically stupid to do this even when there's a perfectly logical answer on one of your questions.. go and hang yourself in shame, you blithering idiot.

Answer 2

v = dist/time

0.25h = 1/4*60 = 20 min

22km/20m = avg v for that section

then do the same thing for 35km & 0.2h
