Answer 1

Answer:

The length of platform is 1000 m

Explanation:

Vinayak is standing at the platform observes that it takes 10 seconds for the train to pass him.

If the length of train is 200 m

So, we can say train takes 10 seconds to cover 200 m

Speed of train, S=200/10 = 20 m/s

Train takes 50 seconds to pass the platform where boy standing.

Time = 50 seconds

Speed = 20 m/s

Distance = speed x time

              = 20 x 50

              = 1000 m

Hence, The length of platform is 1000 m
