Question
A train 400 meters long passes a platform of length 200
meters in 36 seconds. What is the speed of the train in km/h?Solution
Total distance = Length of train + Length of platform = 400 + 200 = 600 meters. Time = 36 seconds. Speed in m/s = Distance / Time = 600 / 36 = 100/6 m/s. Speed in km/h = 100/6 × 18/5 = 60 km/h. Correct option: B) 60 km/h
