    (x+y)*40 = 300 (x-y)*45 = 300 http://www.wolframalpha.com/input/?i=%28x%2By%29*40+%3D+300%3B+%28x-y%29*45+%3D+300

    In math classes, we sometimes measure aircraft speed as miles/minute, but out in real life, everything is measured in miles per hour. That means 40 minutes is 2/3 hour, and 45 min is 3/4 hour.

    Your answers are correct, but generally people use mph (miles per hour), so 425 mph and 400 mph
