A train travelling at 60 mph enters a tunnel that is 5 miles long. The train is one mile long. How many minutes does it take for the whole train to pass through the tunnel?

Answer: E

Explanation: The train is travelling at a speed of one mile per minute, so the front of the train will exit the tunnel in 5 minutes. At this point there is still one mile of train in the tunnel since the train is one mile long. This will take a further one minute to clear the tunnel. Therefore the total time taken is six minutes.
