Question

A TRAIN 210 M LONG TOOK 12 SECONDS TO PASS A 90 M LONG TUNNEL FIND A SPEED OF TRAIN

Answer 1

Answer:

90km/hr

Step-by-step explanation:

Length of train = 210 m.

Length of tunnel = 90 m.

Therefore, total distance = 210 + 90 = 300 m.

Time taken = 12 s.

Therefore, v = s/t

                   = 300/12.

                   = 25 m/s.

                   = 25 X 3600/1000

                   = 90 km/h.

Therefore, the speed of train is 90 km/h
