Question
Two trains are moving in opposite directions at speeds
of 72 km/hr and 54 km/hr. If they cross each other in 15 seconds, find the length of the faster train if the slower train is 150 meters long.Solution
Relative speed = (72 + 54) km/hr = 126 km/hr = 126 × (1000/3600) m/s = 35 m/s. Total distance = relative speed × time = 35 × 15 = 525 meters. Length of the faster train = 525 - 150 = 375 meters. Answer: c) 375 m
