A train 150 m long crosses a platform 350 m long in 40 seconds. Find its speed.
Show answer & explanation
Correct answer: B
Explanation
Given:
Length of the train = 150 m
Length of the platform = 350 m
Time = 40 s
Total distance = 150 + 350 = 500 m
Speed = 500 / 40 = 12.5 m/s
In km/h:
= 12.5 × 18/5 = 45 km/h
