In 2009, Jamaican sprinter Usain Bolt set a world record in 9.58 seconds in a 100-meter sprint.
How fast can the average person run 100?
The average adult male can do it in 15-20 seconds. The average adult female will probably do it in 17-23 years. They have more power, so if they lift weights on a regular basis, someone will definitely be faster.
How fast can humans theoretically run?
New research suggests that humans can probably run at speeds of 40 mph. Such a feat will leave Usain Bolt, the world's fastest runner, in the dust, sprinting 100 meters and recording nearly 28 mph.
