This week's winner is Fight For Love. CONGRATS!!!!!!!!!!!!

RIDDLE: Jake is walking at 2.5 miles per hour. Bob is trying to catch up, and is walking at 3.5 miles per hour. If Jake had a three hour head start, how long will it take Bob to catch up, and how far will he have walked?

ANSWER: Jake has already gone three hours, which at 2.5 miles per hour is 7.5 miles. Since Bob is walking 1 mile per hour faster, it will take him 7.5 hours to catch up. At 3.5 miles per hour, this means he will have walked 26.25 miles.
