Question

a train of length of 100m is crossing a plate form with the speed of 20 meter per minute if the train crosses the plate form in 8 minutes find the length of the platform ​

Answer 1

length of train = 100m

speed= 20m/minutes(20m in 60 secs or 1/3 m/s)

total time= 8minutes or 480 secs.

total distance covered by train in 8 minutes is

480*1/3

160 meter.

this distance also include the length of the train itself also.

it takes 8 minutes to the train to cross the platform means when its front and it's back both should leave the platform. so it takes some time for the train's back to leave the station. so the train's length should be excluded.

so length of platform is

160-100=. 60 meter
