**Ms. Sue**, Sunday, October 9, 2011 at 7:47pmUse this proportion. Cross multiply and solve for x -- the time it takes the front of the train to go through the tunnel.

15/60 = 1/x

15x = 60

x = 60/15 = 4 minutes for the front of the train to go through the tunnel.

It takes the rear of the train the same time.
