A train takes 18 seconds to pass completely through a station 162 m long and 15 seconds through another station 120 m long.The length of the train is
a)70 m b)80 m c)90 m d)100m

Read Solution (Total 1)

Let L be the length of the train.

The train covers a distance of (162 + L) in 18 seconds. The rate is then (162 + L)/18.

The train also covers a distance of (120 + L) in 15 seconds. The rate is then (120 + L)/15.

Presumably, the train is traveling at a constant rate. Therefore, set the two rates equal to each other and solve for L.

(162 + L)/18 = (120 + L)/15
i.e. 90
