Mathy Pac Man Race
In the game Mathy Pac Man Race, Pac Man travels at a speed of 1 mile per minute. There are four ghosts who each travel at a speed of 0.5 miles per minute. All of the creatures are on a 100-mile race track. Every five minutes in the race, Pac Man goes back a mile while the ghosts don't lose their place in the race. At this rate, who will win the race? (Again thanks to Percy Jackson for giving me the idea to write this riddle.)

In five minutes, Pac Man will move five miles, but lose one mile. That means that Pac Man's net speed in miles per five minutes is 4 miles. The ghosts all travel at 0.5 miles per minute, or 2.5 miles per five minutes. Since Pac Man has a higher net speed per five minutes, he will win the race.
