Question
A man travels 60 km at a speed of 30 km/h and returns
the same distance at a speed of 60 km/h. Find his average speed for the whole journey.Solution
Total distance = 60 + 60 = 120 km Time for first part = 60/30 = 2 h Time for return part = 60/60 = 1 h Total time = 2 + 1 = 3 h Average speed = 120 / 3 = 40 km/h
