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