To find out how long it will take for Noah and Ben to be $ \frac{1}{3} $ mile apart, we calculate the difference in their speeds, which is $ 7 mph - 5 mph = 2 mph $. Since they are separating at a rate of 2 mph, we need to find out how long it takes to create a $ \frac{1}{3} $ mile gap. The time is distance divided by speed, so $ \frac{1}{3} $ mile $ \div $ 2 mph = $ \frac{1}{6} $ hour. Converting $ \frac{1}{6} $ hour to minutes gives $ \frac{1}{6} $ hour * 60 minutes/hour = 10 minutes.
