Question

a train 270 M long is running at 80 kilometre per hour how much time will it take to cross a platform 130 m long

Answer 1

total distance covered by the train
= d
= length of the train + length of the platform
= 270 m + 130 m
= 400m

speed = v = 80km/h = 80000m/3600s = 22.23 (approximately)

Time = t = ?

v = d/t
t = d/v
t = 400/22.23
t = 17.9 s (approximately)

so train take
17.9 second
