A train of length 210 metre runs at the speed of 108 km/hr. How long will it take for the train to cross a platform of length 150 metre?

8 seconds

9 seconds

10 seconds

12 seconds

Length of train = 210 m.

Length of platform = 150 m.

Speed of train=108 km/h=108*5/18=30m/s

Total length covered by train= length of train+length of

platform=210+150=360m.

So time taken to cross the platform=Length covered by train/Speed of train=360/30=12 sec
