Question

A train 150 m long is running at 72 km/hr. It crosses a bridge in 13 seconds. Find
the length of the bridge.
​

Answer 1

Step-by-step explanation:

given:-

• train length = 150m
• speed = 72 km/hr
• Cross time = 13 seconds

To Find :-

• the length of the bridge.

Solution :-

=> speed = 72km/h = 72×5/18 = 20m/s

=>. bridge length = 20×13 = 260

=> bridge length - train lenth

=> 260 -150

=> bridge length = 110m

Hence the length of the bridge is 110 m.
