10. Link from Wiki Answers on the top speed of Chimp vs Human
The AVERAGE top speed of a chimpanzee on the ground is about 25mph*.
The fastest speed ever recorded for a man was about 27mph.
Note that the chimp speed was an average, this means there are both faster and slower individuals. The human record was a single man and there was no faster individual.
It is fair to say that on average they would be about the same. The same would also be true for the time at which both species can maintain this speed. Humans are moderately poor sprinters, as are chimpanzees.
Ever try to chase someone riding a bicycle? The average speed of a single speed bike is around 15 mph. The average walking speed is around 3 mph.
Bottom line, an average chimp can outrun an average human especially since the human will keep looking back to see if the chimp is gaining on them,....which he WILL be because he has nothing else on his mind but his target.
Chimps are also much stronger than humans and can easily win in a hand to hand contest.
