A 400 m long train is to cross a railway bridge over the river Godavari. If the bridge is 2.1 km long and the train passes over the bridge at a uniform speed of 36 km/hr, how much time does the train take to cross the bridge?

length of the train =400m
length of bridge=2.1km=2100m
total length = 400m+2100m=2500m
speed of train =36km/hr
=36*5/18=10m/s
therefore time taken by the train to cross the bridge=2500/10=250secs
length of bridge=2.1km=2100m
total length = 400m+2100m=2500m
speed of train =36km/hr
=36*5/18=10m/s
therefore time taken by the train to cross the bridge=2500/10=250secs
