who won?

[Charles510]

When Peter and Bill ran a 100-meter race, Peter won by five meters. To give Bill a chance to win, they raced again, but this time Peter started five meters behind the starting line.

Each man ran the race at the same speed as in the first race.

What were the results of the second race?
