# A train 150m long crosses a pole in 5 seconds. Find the time taken by the train to cross a bridge 200m long

Please find below the solution to the asked query:

Given : A train 150 m long crosses a pole in 5 seconds . So,

Distance = 150 m and Time = 5 sec

We know : Speed = $\frac{\mathrm{Distance}}{\mathrm{Time}}$ , Then

Speed of train = $\frac{150}{5}$ = 30 m / sec

Also given : train to cross a bridge 200 m long , So total distance train has to cover = 200 + 150 = 350 m

Therefore,

The time taken by the train to cross a bridge 200 m long = $\frac{350}{30}=\frac{\mathbf{35}}{\mathbf{3}}\mathbf{}\mathbf{=}\mathbf{}\mathbf{11}\mathbf{.}\mathbf{67}$
