72 * 1000/3600

72 * 5/18

4 * 5

20 m/s

Therefore the train takes 1 second to travel 20m

Therefore to travel 200m the train will take

As to pass the platform 400m long the train has to travel 600m (length of the train + length of the platform)

Therefore to travel 600m with a speed of 20m/s the train will take

The formula used here is

Therefore ...................

The Brainliest Answer!

72km/hr = 72 * 5/18

= 20m/sec

1) Time = Distance/Speed

= 200/20

=

2) Time = Distance/Speed

= 600/20 (600 = Length of the train + Length of the platform)

=
