Question

A 200 m long train crosses a 400 m long bridge with the speed 30
km/h. Calculate the time taken by the train to cross the bridge.

Answer 1

Total distance = 400+200= 600

Speed =30 km/h= (30*1000)/3600= 25/3m/s

Time= D/T

=600/25/3

=600*3/25

=72s

Ans. It will take 72 seconds to cross the bridge.
