Question

A train is 100m long is moving with a speed of 72kmph the time taken by the train to cross a pole in the stations

Answer 1

1 km = 1000 m

total distance = 100 m

speed = 72 kmph = 72 x 5/18

= 20 m/s

time = distance / speed

= 100/20

= 5 sec [ approx. ]

so, the time taken is 5 second.

time = distance / speed

= 100/20

= 5 sec [ approx. ]

Therefore, time taken is 5 second.
