A train that is 80 meters long travels 240 meters in 6 seconds. How many seconds would it take the train to pass through a 480 meter long tunnel.
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
