Question: Biff and Kenneth decide to compete in a 500-yard rowboat race. If Biff rows at a speed of 50 yards per minute and Kenneth rows at a speed of 51 yards per minute, how many yards past the finish line will Kenneth be when Biff crosses the finish line? Think carefully first, then make a decision:

Traveling at 50 yards per minute, Biff can travel 500 yards in 500 / 50 = 10 minutes. In 10 minutes, traveling at 51 yards per minute, Kenneth can travel 10 * 51 = 510 yards. Thus, Kenneth will be 510 - 500 = 10 yards past the finish line when Biff crosses the finish line. So the answer is 10.
