Two towns are 243 miles apart. Bob and Joe each start in one of the towns at noon and drive towards each other with uniform motion. Bob drives 45mph, Joe drives 65mph. When do they meet? Where do they meet?

Their relative velocity is 45 + 65 = 110 mph. At that rate, they cover 243 miles in 2 hours, 12 and a half minutes. Bob has covered 99 1/2 miles; Joe has driven 143 1/2 miles.
