Question

A train 120 m long is running at a speed of 54 km/hr in how much time will it pass a bridge of 180 m long ?​

Answer 1

Answer:

The speed of the train = 54 kimph = 54×5/8 =15 m/sec

Total distance to cover = length of the train + length of the bridge

=120 + 90 = 210 m.

Time taken to cover 210 m = 210/15 = 14 sec.

Hope this is helpful for you.
