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.
Average speed as you can see really depends on the distance, once you've decided this then Yih can use my rule of thumb of twice pros for a feel. Good luck! Depends, on how far you are going and how fast you are. Running a 4 minute mile is extremely fast for a human. Only about 800+ people have done it. That averages to 15 mph. Elite Marathoner's run roughly 5 minutes per mile for 26.2 miles.
