Most adults can run at about 7 mph in a short distance. That would be at top speed. If the same person ran a mile it would probably take about 30 to40 minutes depending if they are tired or fully energized. http://wiki.answers.com/Q/How_fast_can_an_average_person_run. it depends for how long but just a couple seconds i would guess around 15mph im pretty sure that if your physically able to run you could run atleast 15mph for a couple of secounds.
Credit: stockxpert. Humans could perhaps run as fast 40 mph, a new study suggests. Such a feat would leave in the dust the world's fastest runner, Usain Bolt, who has clocked nearly 28 mph in the 100-meter sprint. The new findings come after researchers took a new look at the factors that limit human speed. Their conclusions? The top speed humans could reach may come down to how quickly muscles in the body can move.
