You are travelling to point B from point A at a speed of 30mph. You travel back to point A from Point B (taking the same route) at 60mph. What is your average speed?

(In reply to Just for arguement by Leming)

Leming u can do this  provided the time for which he travelled 60mph and 30mph are equal.

i.e if he has travelled for n hours with 60 mph and for n hours with 30mph then the avg speed will be 60+30/2 = 45mph.

In this case u can't do this
