Assume that you are standing near a railway track and you happen to see a train which is of length 200 m and runs at a speed of 36 km/hr coming towards you. So, in what time this train will cross you? Give the answer in seconds.
20sec
We know that Time = Distance/Speed
Here, distance is the length of the train =200 m
And speed =36 km/hr or 36×518=10 m/s
So, time =20010=20 seconds
