How long does it take for a mile long train to go through a mile long tunnel if it goes 30 mph?
4 minutes. The last car on the train is the best way to think about it. That car has to travel the length of the train(1 mile) and also the length of the tunnel( also 1 mile). The total distance would be 2 miles, obviously. So if the train were traveling at 60mph it takes 1 minute to go 1 mile, but since it is going 30mph, it would take two minutes to go 1 mile.

A train is 180m long and travels at a speed of 36km per hour How long will it take to pass through a tunnel 90m long?
36km/hour = 10m/second Assuming you're calculating the time taken from the moment the front of the train enters the tunnel to the time when the back of the train exits the tunnel, you're looking at a total distance of 180+180+90 = 450m Hence the time taken to pass through the tunnel completely would be 450/10 = 45secs.
How long will it take a two mile long train going 12mph to get completely through a mile tunnel?
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.
How long will it take a one mile long train to get through a one mile long tunnel of it is going at 15 miles per hour?
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
Train is135m long average speed 120 kmh 50 seconds it passes through tunnel what is the length of the tunnel?
120 km/h = 120,000m/hr = 33.333 m/s Distance travelled in 50 seconds = 33.333 * 50 = 1666.666 metres Tunnel length = distance travelled - train length - 1666.666 - 135 = 1531.666metres
How long will it take a mile long train going 20 Miles per hour to get completely through a 2 mile long 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)

A train 1 mile long moving at a rate of 1 mile per hour enters a tunnel 1 mile long How long does it take the train to pass completely through the tunnel?
2 hours. If the train is one mile long and going 1 mile per hour through a mile long tunnel, in one hour the train would be completely inside the tunnel, since they are the same length and the train is only going one full tunnel length(mile) per hour. It would then take another whole hour for the end of the train to leave the tunnel, bringing the train completely out of the tunnel.
A train is a mile long and so is the tunnel so how long until the train is out of the tunnel?
There is no way to answer correctly without knowing where the train is relative to the tunnel and the speed that the train is traveling.
If a train is 1 mile long and is traveling at 1 mile per minute how long will it take the train to go through a tunnel that is 1 mile?
Well, isn't that a lovely little puzzle! If the train is 1 mile long and it's traveling at 1 mile per minute, it will take a total of 2 minutes for the train to completely pass through the 1-mile tunnel. Just imagine the train chugging along steadily, enjoying the journey through the tunnel, and coming out the other side with a happy little toot of its whistle.
