L&T Company Numerical Ability Time Distance and Speed

The length of the bridge, which a train 160 metres long and travelling at 63 km/hr can cross in 24 seconds, is:
A)280 m B)190 m C)200 m D)260 m

Read Solution (Total 1)

let x be the length of bride
speed of train = 63* 5/18 = 35/2m/s
length of train = 160 m
time taken to cross bridge = 24s

speed = distance / time
now,
35/2 = (x + 160) / 24
upon , solving
x = 260 m
