You can put this solution on YOUR website! At a NASCAR track, the distance per lap is 2 miles. Lou drives his car at a constant rate of 160 miles per hour. Red drives his car at a constant rate of 170 miles per hour. How long will it take before Red gains 2 laps in relation to Lou?
------------
2 laps = 4 miles
Red is gaining at 10 mph (170-160)
4 miles/10 mph = 0.4 hours = 24 minutes
