A train is 140m long is running at 60 kmph. In how much time will it pass a platform 260m long.

A. 12sec

B. 24sec

C. 36sec

D. 6sec

Answer: Option B

Solution(By Examveda Team)

Length of the train = 140 m
Length of the platform = 260 m

Total distance covered = 140 m + 260 m
= 400 m

Speed of the train = 60 km/hr
= 60 * (1000 / 60) m/sec
= 50 / 3 m/sec

Time taken to pass a platform = Total distance covered / Speed of the train
= 400 / (50/3) m/sec
= 1200 / 50 m/sec
= 24 m/sec
