Last Week's Puzzle
Sam and Lori decide to run a 100 yard race. Lori wins by 10 yards. They race again, but to even things up, Lori begins 10 yards behind the start line. Assuming that both run with the same constant speed as before, who wins?
Answer: Lori wins again. In the first race she ran 100 yards in the time it took Sam to run 90. Therefore, in the second race, after Sam has gone 90 yards, Lori will have gone 100, so she will be alongside him. Both will have 10 more yards to go. Since Lori is the faster runner, she will finish before Sam.
