Question

A train 600 m long, travelling at a speed of 60 km/h, passes a bridge in 90 s. What is the length of the bridge​

Answer 1

Answer:900 m

Step-by-step explanation:

Let the length of the bridge be x m.

A.T.Q.

Speed in m/sec.=60*5/18

=50/3 m/sec.

Distance to cover=50*90/3

=1500 m

600 m+x=1500 m

x=1500 m-600 m

x=900 m
