Speed of the train-60 km/h
in order to cross the bridge the train has to cover its own length and the bridge length.
So total distance becomes=800+400m=1200m=1.2km
Speed=Distance /Time
Time ×Speed =Distance
Time=Distance / Speed
So,
Time taken by the train=1.2/60 hour (1.2/60)×3600 seconds=72 seconds.
Ans) The time taken by the train to cross the bridge is 72 seconds

The answer was 1.2/60in hr. So if we convert into seconds,we should multiply by 3600
