Question

5. A train is running at a uniform speed of 60km/he. If the bngth of the train is 73m, then the time taken by the train to cross a bridge 87m long is-?​

Answer 1

Answer:

9.6s

Step-by-step explanation:

speed of train=60km/h

length of the train =73m

length of the bridge = 87m

Total distance the from the head train to completely cross the bridge = 73+87 = 160m

So speed = distance/time

i.e time=speed/distance

= 160m ÷ 60km/h

= .16km ÷ (60km/60*60s)

= 9.6s
