In an air race over 100 km the spitfire beat the Messerschmidt by exactly 10 kms. In order to show the British sense of fair play, the spitfire then started 10 kms and 101 meters behind the start line. The race was then run again, and both planes maintained exactly the same speed as in the previous race. Which one won this time?
