A Train Passes a 110 M Long Platform in 40 S and a Boy Standing on the Platform in 30 S. the Length of the Train is - Mathematics
A train passes a 110 m long platform in 40 s and a boy standing on the platform in 30 s. The length of the train is
Let the length of train = x m
∴ Speed of train while crossing a platform = `(110+"x")/40`m/s
and speed of train while crossing a boy = `"x"/30`
⇒ 4x = 330 +3x
∴ x = 330 m
