Question
Two trains A and B, were proceeding in the same
direction on parallel tracks at 20 km/hr and 92 km/hr respectively. A man noticed that it took exactly 15 seconds for the faster train to pass by him. What is the length of the faster train?Solution
Relative speed = (92 – 20) km/hr = 72 km/hr => 72 × (5/18) = 20 m/sec Length of the faster train = 20 × 15 = 300 m
