Question
Two trains of lengths 280 meters and 320 meters are
running in the same direction at speeds of 54 km/h and 72 km/h, respectively. How much time will the faster train take to completely cross the slower train?Solution
Relative speed = 72 km/h - 54 km/h = 18 km/h = (18 × 1000) / 3600 = 5 m/s. Total length to be covered = 280 + 320 = 600 meters. Time taken = Distance / Speed = 600 / 5 = 120 seconds. Correct option: D
