Two trains are on a head on collision course. The trains are currently 65 miles apart. The north bound train is traveling at 55 miles per hour and the south bound train is traveling at 80 miles per hour. What is the distance between the trains two minutes before they collide?

55 + 80 = 135mph
Divide by 60 minutes = 2.25 miles per minute, therefore 2 minutes before impact they will be 4.5 miles apart
