Jatin was trying to take a short cut through a very narrow tunnel when he heard the whistle of an approaching train behind him. Having reached three-eights of the length of the tunnel, he could have turned back and cleared the entrance of the tunnel running at 10 km per hour just as the train entered. Alternatively, if he kept running forward, the train would reach him the moment he would jump clear of the tracks. At what speed was the train moving?
A train travelling at a speed of 76 mph enters a tunnel 9/2 miles long. The train is 1/4 mile long. How long does it take for the train to pass through the tunnel from the moment the front enters to the moment the rear emerges?
A train travelling at a speed of 80 kmph enters a tunnel that is 0.5 km long. The length of the train is 0.25 km. How long does it take for all of the train to pass through the tunnel, from the moment the front enters, to the moment the rear emerges?
A 110 yard long Christmas train travels at 30 mph, through a tunnel, into Santa’s grotto. If the length of the tunnel is half a mile, how long will elapse between the moment the front of the train enters the tunnel and the moment the end of the train clears the tunnel?
A 500 mtr long train, travelling at 100 kph, enters a five km long tunnel.
How long will elapse between the moment the front of the train enters the tunnel and the moment the end of the train clears the tunnel?
