Book Maths Puzzle

A person travels from A to B at a speed of 40 km/hr and returns by increasing his speed by 50%. What is his average speed for both the trips?

Read Solution (Total 1)

speed from a to b = 40km/hr.
speed from b to a = 40+((50/100)*40))=60.
hence, average speed is (2*40*60)/(40+60)=48km/hr..
