A train is moving at a speed of 132 km/hour. If the length of the train is 110 meters, how long will it take to cross a railway platform 165 meters long.

A. 7 second

B. 7.5 second

C. 8 second

D. 8.5 second

Correct Answer :

B. 7.5 second


As we need to calculate answer in seconds, so first convert speed into meter/sec.
we know 1 km/hr = 1*(5/18) m/sec
So, Speed = 132* (5/18) = 110/3 m/sec
Distance need to be covered in passing the platform =
Length of train + length of platform = 110 + 165 = 275 meters
Time = Distance/Speed
rightwards double arrow T i m e equals 275 cross times 3 over 110 equals space 15 over 2 equals 7.5 space s e c
