A 200m long train crosses a 400m long bridge with a speed of 36km/hr . Calculate the time taken by train to cross the bridge? plz give me the answer with explaination
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
speed of the train(v)=36km/h
let L be the length of the train
and S be the length of bridge
