wo trains leave Chicago headed in opposite directions. The first train heads west at 75 miles per hour. The second train heads east at 60 miles per hour. How long will it take for them to be 405 miles apart?

75+60=135 mph=rate at which the two trains are traveling apart
travel time=distance/rate=405/135=3
How long will it take for them to be 405 miles apart? 3 hrs
