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.

It took Kevin 10 hours to pass Sue, given there was no stopping involved.
Sue had a 100 mile lead over Kevin, but Kevin's car goes 10 miles faster. 100/10 = 10, so 10 hours Ans.
