Question

What is the speed of a train of 80 metre long train passes a railway station platform of 120 metres length in 20 seconds?

Answer 1

Answer:

10 m/s

Explanation:

As given

• Length of Train = 80

• Length of platform = 120 m

• Time = 20 sec

Now the distance train have to cover to pass the platform

= Length of Platform + Length of Train

= 200 m

As when the last compartment will cross the platform , then only we can say it have crossed the platform.

Now

Speed = Distance ÷ Time

= 200 ÷ 20

= 10 m/s
