Depends on what "out of" means.
At 60 miles per hour (one mile per minute), a train entering a mile-long tunnel will first emerge one minute later.
But for the full one-mile length of the train to pass through the tunnel and exit will take another minute, totaling two minutes from the time the first car enters to the time the last car leaves.
just as a 1 cm long train takes 2 minutes for the front and the back to completely traverse the tunnel
i think its about 4900 hours.im not good at math. Right on that! The train must travel 3 miles to go thru the tunnel and to the other end. Math is 20 miles in 60 mins......therfore 3 miles in 9 mins (60/20*3)
5 min
Tsugaru Strait, Japan: 53,850 metres (33.5 miles)
4 minutes
From the time the front of the locomotive enters the tunnel . . .-- The front of the locomotive traverses the 1-mile tunnel, bringing the center of the train to the entrance.-- The center of the train traverses the 1-mile tunnel, bringing the end of the train to the entrance.-- The end of the train traverses the 1-mile tunnel.In all, the train has to travel 3 miles. At the rate of 12 mph, it takes (3/12) = 1/4 hour = 15 minutes.
The present Cascade Tunnel is 7.79 miles long. The original Cascade Tunnel was 2.63 miles long.
If you are timing from when the train first enters the tunnel until the last car exits the tunnel, then the train would travel 2 miles during this time.So 2 mi / (15 mi/hr) = (2/15) hr * 60 (min/hr) = 8 minutes
No such tunnel exists.
The Eisenhower Memorial Tunnel is 1.6 miles long...almost two miles long.
Depending on the tunnel (there are three), they are 1.4 - 1.5 miles long.
The world's longest canal that is also a tunnel is the Rove tunnel located in France. It was built in 1974. The longest tunnel in the world is a railroad tunnel that is 35 miles long through the Swiss Alps.
