Question

A 600 m long train is running with a speed of 54km/hr. in how many time will it pass a tunnel 200m long?

Answer 1

In order to cross a tunnel, the train will have to cover a distance equal to the sum of its length and that of the tunnel.

the train is 600 m long. and the tunnel is 200 m long.

So the total distance the train will be having to travel is equivalent to 800m.

So let's find out how much the train will take to cover those 800m.

the speed of the train = 54km/h = 15 m/s

time = 800/15 = 53.33 seconds answer.
