Train Drain

On my local railway track there is a tunnel which is 5 miles long. A train, which was 440 yards long, entered the tunnel at a speed of 50 miles per hour. How long did it take for the whole of the train to pass completely through the tunnel?

  • 6 mins 18 seconds, that is.

  • Paul

    The length of the train is 440 yards = 1320 feet = .25 miles + the length of the tunnel 5 miles / 50 miles per hour = .105 x 60 minutes = 6.3 minutes 30% of 1 minute = 18 seconds so the answer is 6 minutes and 18 seconds.

  • Dude

    6 minutes and 18 seconds is correct, Jimmy Barcus.

    The train has to effectively travel 5.25 miles at 50 mph. Time = Dist ÷ Speed = 5.25 ÷ 50 = 0.105 hours = 6.3 minutes = 6 minutes 18 seconds.

    You’re today’s winner.
