A train of length 250 m runs at a speed of 70 km/hr.

A train of length 250 m runs at a speed of 70 km/hr. What will be the time taken to cross any stationary object standing at the railway station?

Quiz

Answer/Solution

12.86 sec

Steps/Work

EXPLANATION:
Length of train = 250 m, speed of train = 70 km/hr
Length of train is always considered as distance, and hence here distance = 250 m
1) First convert speed of km/hr into m/s
Speed of train = 70 x 5 = 19.44 m/s
18
2) We know that,
Speed = Distance /Time
Time taken to cross stationary object = 250 / 19.44
Time taken to cross stationary object= 12.86 sec
