Question

A train of some length passes the platform of length 400 m in 45 seconds . Find the length of train if the speed of train is 66 km/hr .
A. 476 m
B. None of these
C. 428 m
D. 410 m

Answer 1

Correct Answer - D
Speed of train in m/s = `66 xx (5)/(18) = 18` m/s
Let length of train be x m
ATQ ,
`(400 + x)/(45) = 18`
x = 810 - 400 = 410 m
