Sue left her home at 6 A.M. driving her car at the rate of 50 miles per hour. At 8 A.M. her brother Kevin drove after her along the same highway, traveling at the rate of 60 miles per hour, in how many hours did Kevin pass Sue?
I got 10 hours but that is when they're at the same distance, so would the answer be 11?
