Question

Two cars travel at the same speed to different destinations. Car A reaches its destination in 40 minutes. Car B reaches its destination in 50 minutes. Car B travels 9 miles farther than Car A. How fast do the cars travel?

Answer 1

54 mph

Explanation:

Since Car B travels 9 more miles in 10 more minutes, you would need to multiply 10 by 6 and 9 by 6 to get 54 miles per 60 minutes or 54 mph. And this would work because Car A would travel 36 miles and Car B would travel 45 miles and 45 - 36 is 9.
