Question

a train 50 m long passes a pole in 5 seconds what is the speed of the train and time taken to cross bridge that is 450 m long

Answer 1

Answer:

Let the length of the bridge be L.

Total distance covered by the engine to cross the bridge d=50+L

Speed of train v=36 km/h=36×

18

5

=10 m/s

Time taken t=35 s

Using d=vt

Or L+50=10×35

⟹ L=300 m
