Question 345720: how long will it take a car going 65 miles per hour to catch up with a car going 55 miles per hour if it starts 1 hour behind Answer by solver91311(24713) (Show Source):
In one hour, the 55 mph car will have gone 55 miles. The 65 mph car will use up 55 mph of its speed just staying even with the slower car and then only has 65 minus 55 equals 10 mph to use to catch up. How long does it take to go 55 miles at 10 mph?
