CHALLENGE 105 QUESTION AND ANSWER:
Jack and Jill were racing, but it was no contest. Jack beat Jill by 10 yards on a 100-yard course. Jill suggested that for the second race, Jack should start 10 yards behind the starting line- she figured that would give her a fair chance, since he had won by 10 yards. Who won, and by how much?
ANSWER:
Jack won by one yard. He can run 100 yards while Jill can run 90, so with 10 yards left, the two of them are tied.
