Question

A train travelling at a speed of 80 km per hr passes a bridge of 350 metres long in 36 seconds ..find the lenght of train

Answer 1

Speed of the train = 80 kmph = (80 x 5/18) mps = 200/9 mps

Let the length of the train = x meters

Speed = Distance/Time

Speed = 200/9 mps

Time = 36 sec

Distance = ?

Distance = speed x time = 200/9 x 36 = (200 x 4)m = 800m

Therefore the distance = 800m = Length of the bridge + Length of the train

Length of the train = 800m -Length of the bridge = 800m - 350m = 450m

Therefore, the length of the train is 450m.

450 m
