Question

A train 250 m long is moving at a speed of 45 km/h. How much time will it take to pass a bridge of length 350m?​

Answer 1

Answer:

Lenght of train =250m

Speed =45 km/hr

Lenght of bridge =350m

Step-by-step explanation:

Converting the km into metres and hr into seconds (45km/hr)

45000m 3600 seconds

Now speed =d/t in one second

45000/3600=12.5m/s

Now t =d/t

I. E. Lenght of bridge - length of train

=350-250

=100m

Therefore to cover 100 m time taken will be

100/12.5=8 seconds
