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?

For a train of length (1/4) mile long to cross a tunnel of (9/2) mile long it has to travel a distance of (9/2) + (1/4) = 4.75 miles ie., length of the tunnel + length of the train. Therefore to find the time taken for this ===> distance / speed = Time 4.75/76 = 0.0625 hours = 225 seconds
