The speed of a train is 36 km/hr. Length of the train is 100 metres. In how much time (in seconds) it will cross a platform of length 200 metres?
Show answer & explanation
Correct answer: C
Explanation
Given:
Speed = 36 km/h
Length of the train = 100 meters
Length of the platform = 200 meters
According to the formula:
Time = Total Distance / Speed
Total Distance = 100 + 200 = 300 meters
Speed = 36 km/h = (36 × 1000 / 3600) = 10 m/s
Time = 300 / 10 = 30 seconds
