Question

A train is running at a speed of 48 km/h . How long will it take to reach a signal at a distance of 80 m from the standing platform?

Answer 1

Answer:

The train is running at a speed of 42kmph. So the distance covered by train in meters per second is:

42*(5/18)=35/3 m/sec

Now the time required to the train to cross a man of is the same amount of time that train will take to cross itself that is 280 m.

So 280*(3/35) = 24 seconds.
