a train hundred metre long is movie with a velocity 16 kilometre per hour find the time it takes to cross 1 kilometre long bridge.

  4 minutes 7 1/2 seconds

Step-by-step explanation:

For the train to completely cross the bridge, it must travel a distance equal to the sum of its own length and that of the bridge.

  time = distance/speed

  time = (1 +0.1) km/(16 km/h) = 1.1/16 h ≈ 0.06875 h

It will take the train 0.06875 hours, about 4 minutes 7 1/2 seconds, to cross the bridge.
