<human>:  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?
<bot>: How many minutes does Biff take to travel 500 yards? ** Traveling at 50 yards per minute, Biff can travel 500 yards in 500/50=<<500/50=10>>10 minutes.
How many yards can Kenneth travel in 10 minutes? ** In 10 minutes, traveling at 51 yards per minute, Kenneth can travel 10*51=<<10*51=510>>510 yards.
How many yards past the finish line will Kenneth be when Biff crosses the finish line? ** Thus, Kenneth will be 510-500=<<510-500=10>>10 yards past the finish line when Biff crosses the finish line.
