Question: Two boys, Trevor and Tyler, are running a 100 meter race. The first time they race Trevor beats Tyler by 5 meters. To make things fair, the next time they race Trevor stands 5 meters behind the starting line.
Who wins the second race (assuming they run the same speed as the first race)?
Answer: Trevor wins again. In the first race Trevor ran 100 meters in the time it took Tyler to run 95 meters. So in the second race when Tyler is at the 95 meter mark Trevor will also be there (since 100 - 5 = 95). Since Trevor is faster he will pass Tyler in the last 5 meters of the race.
