What is the time taken by a train running at 18 km/h to cross a man standing on a platform, length of the train is 120 m?
Correct Answer: 24 s
Explanation:
Speed of the train = 18 km/h = 18 x 5/18 m/s = 5 m/s
Distance covered = Length of the train = 120 m
∴ Time taken by the train to cross the man = Distance/Speed
= 120/5 = 24 s
