Speed=distance / time
Data:
distance=240 m
time=6 s

Speed of this train=240 m / 6 s=40 m/s

The train pass through 480 meters of tunnel, therefore the distance will be:
distance of the tunnel + distance of the train= 480 m + 80 m=560 m

speed=distance / time ⇒ Time=distance / speed
Data:

distance=560 m
speed=40 m/s

Time=560 m/ (40 m/s)=14 s

Answer: 14 seconds will take the train to pass through a 480 m long tunnel.

Answer:

Speed=distance / time

Data:

distance=240 m

time=6 s

Speed of this train=240 m / 6 s=40 m/s

The train pass through 480 meters of tunnel, therefore the distance will be:

distance of the tunnel + distance of the train= 480 m + 80 m=560 m

speed=distance / time ⇒ Time=distance / speed

Data:

distance=560 m

speed=40 m/s

Time=560 m/ (40 m/s)=14 s

Answer: 14 seconds will take the train to pass through a 480 m long tunnel
