Atrain traveling 30 miles per hour reaches a tunnel which is 9 times as long as the train. if the train takes 2 minutes to completely clear the tunnel, how long is the train? (1 mile= 5,280 feet)

Let x = length of the train 9x = length of the tunnel Given speed at 30 mph and time to completely clear the tunnel which is 2 minutes 9x + x = (30 mi/h)(2 min) (h/60 min) Therefore x = 1/10 mi or 528 feet
