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.

A high speed train travels south for 2.00 h for a distance f 454 km What is its average velocity?

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
What could be the length of the train while the train travelling speed 60km per hour It takes 2 min to pass 1.5 km Cave?
I am not sure if this question is correct, but my interpretation of the situation would be as follows. We consider the time it takes to pass through a tunnel to be the time that it takes from when the very front of the vehicle enters the tunnel to when the very end of the vehicle leaves the tunnel. Imagine a driver at the very front of the train and a conductor at the very back of the train. The distance between them would give the length of the train. At the beginning of the 2 minutes that it takes to pass through the tunnel the driver is at the opening of the tunnel. At the very end of the 2 minutes the conductor is at the exit of the tunnel. At that time the driver is still a trains length in front of the conductor. Therefore, in the 2 minutes the driver has travelled the length of the tunnel (1.5km) plus the length of the train (we will call this x). We are going to use the formula speed = distance travelled/time which rearranges to distance travelled = speed * time speed(km/h) = 60 distance travelled (km)= 1.5 + x time(minutes) = 2 time is in minutes so we must convert speed to minutes: 60km/h = 1km/min substituting these into distance travelled = speed * time gives: 1.5 + x = 1 * 2 1.5 + x = 2 x = 0.5 So, the length of the train must be 0.5 kilometres, which seems very high.
If a train travels for 4 5 hours at a rate of 40 mph what is the distance the train will travel?
Just multiply the 45 hours by the speed.
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.
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.
A high speed train travels with an average speed of 227 kmh The train travels for 2 h how far does the train travel?

Is there a train that goes underewater and takes you to Paris from London?
Kinda-sorta. There's a tunnel (well actually three separate pipes) that goes under the English Channel, and there's a train that travels between Britain and France through that tunnel.
A train one mile long travels at a rate of one mile per minute through a tunnel that is one mile long?
2 hours
What is the quicker way to get to the South of France?
The quickest way to get to France would be by Train via the Chanel Tunnel, or by a fast Ferry that operates between March until October from Portsmouth to Cherbourg. If you live be Dover, the Dover to Calais ferry would be an option too. I have also found a flight listed from Bristol to Dinard Airport. I hope this has helped you.
How fast can a normal train travel?

What is the name of the train that goes through the tunnel to Paris?
The eurostar.
What is the preposition of the sentence the train traveled through the tunnel?
The preposition is through.The noun 'tunnel' is the object of the preposition.Through
A train travels 495km in 4 hours What is its average speed in km per h to 2 sig fig?
The train travels at 123.7 km/h
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.

How long under water on the Eurostar?
A train takes approximately 25 minutes to go through the Channel Tunnel. Eurostar is the brand name of the company running high speed trains London-Paris and London-Lille-Brussels through the Channel Tunnel. Eurostar uses the stations: St. Pancras (London), Gare du Nord (Paris), Bruxelles Midi (Brussels) and Lille Europe. Currently these are the only passenger trains operating through the tunnel. The Eurostar takes 2 hours 15 minutes between London and Paris.
