Question

A train 400 m long is moving with the velocity of 50 km/ hr . Find the time it takes to cross the bridge which is 600m long ?​

Answer 1

Answer:

Let the length of the train be L.

Total distance cover by the engine to cross the bridge d=400+L

Speed of train v=30 m/s

Time taken t=20 s

Using d=vt

or 400+L=30×20

⟹ L=200 m
