Answer 2

Given: A train 250m long is running at 80km/hr.

To find: We have to find the time required to cross a platform 150m long.

Solution:

The total distance is equal to 150+250=400 meters.

The speed of the train is 80km/hr.

Converting it in m/s we get-

80×1000/3600=22.22m/s.

Thus, the speed of the train is 22.22 m/s.

Thus the train can travel 22.22 meters in 1 second.

So, 400 meters will be travelled by train in 400/22.22=18 seconds.

Thus, 18 seconds will be required to cross a 150-meter long platform by the train.
