Question

An express train, 440 metres long, is running with a speed of 90 km/h. In how much time will it pass a tunnel 110 metres long?​

Answer 1

Answer:

22 seconds

Step-by-step explanation:

Length of train = 440 metres

Length of tunnel = 110 meters

Distance = (440+110) metres = 550 metres

Speed = 90 km/h = (90 × 5/18) m/s = 25 m/s

Time taken = (550/25) s = 22 seconds

Answer 2

Answer:

22 second

Step-by-step explanation:

Length of train=440 metre

Length of tunnel=110m

Distance =(440+110) metre=550m

Speed=90 km/h=(90 ×5/18) m/s=25m/s

Time taken=(550/25) S=22sec.

This is correct answer
