The Eurotunnel connects Great Britain and France, passing under the English Channel. A train leaves France with an average velocity of 110 km/h and travels 37 km in the tunnel. How long is the train in the tunnel?
37 km / 110 km/ hr = 37/110 hr
110/60 =1 5/6 Km the train travels in 1 minute. Therefore,
37 / 1 5/6 =37 X 6/11=20 minutes and about 11 seconds in the Eurotunnel.
