The speed of the train is v = 36 km/h =36000/3600=10 m/s,

L is the length of the train,

S is the length of the bridge.

The time of passing the bridge begins when head end of the train enters the bridge and ends when its rear end leaves the bridge, therefore, the distance is s=L+S=200+400=600 m

t=s/v =600/10=60s

speed of the train(v)=36km/h

=36*5/18

=10m/s

let L be the length of the train

and S be the length of bridge

Therefore, distance(s)=L+S

=200+400

=600m

time(t)=s/v

=600/10

=60s ans.
