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

Answer:

train length = 150m

》 speed = 72km/h = 72×5/18 = 20m/s

》bridge length - train lenth=

》20×13 = 260 -150

》 bridge length = 110m

Answer 2

Answer:

110 m

Step-by-step explanation:

72 kmph=20 mps (72×5/18)

crossing bridge means crossing bridge+it's length

let length of bridge is x

total length to cover is 150+x

t= (150+x)/20= 13

solving we get x=110 m
