it depends on the age group. 15 seconds is a decent time for a grade school 100 meter dash, but it would be a decent time for a high school 200 meter dash.

14.87

14.87 that's wired. im 15 and i ran about 2.5s in the 20 yd dash. for 12 year old i think you should run a least 3s at the fasted

The World Record is 5.56seconds held by Donovan Bailey of Canada. He ran this in 1996.

Florence Griffith Joyner has the record for the fastest times in the women's 100 meter race. She currently holds the top 3 fastest times of 10.49 seconds, 10.61, and 10.62 seconds.

what is the average speed of an 8 year-old at running

35 secs is great keep on going but im running it in 34 at the moment

A good time for a 9 year old boy in the 400 dash is 1-1:15 minutes. If competing the time should be under 1 minute.

Oh my gosh, yes! If you're running that as an 11 year old, imagine how fast you would be in high school! The average time for an 11 year old girl in the 100m is like, 16-17 seconds or something. So yeah. Keep running and you could be kicking some butt by the time your a freshman in high school.

Rule of thumb marks for youth 100 meters- boys

Age Excellent Good Needs Improvement

<10 14.5 15.6 16.6

<12 13.9 14.2 15.7

<14 12.5 12.7 13.0

<16 11.0 12.0 12.2

<18 10.4 11.4 11.6

These times are based on athletes wanting to compete at the highest levels. Very few 10 and under and 12 and under runners compete at the 100 meter distance it is better to factor these times down to 40 meter splits or better yet for common American 40 yard splits>

10.23 by Tamunosiki Atorudibo of Nigeria (DOB: 21/3/85) - 23/3/02

I'm 12 yrs old and my best time is 13.32 (i'm a girl) and I have competed in races and won overall. I think an average time would be 14 or 15 seconds.

That was Jim Hines of the United States at the U.S. National Championships in June, 1968 with a hand timed 9.9. He then became the first to run an electronically timed 100m under ten seconds at the 1968 Summer Olympics with a 9.95.

They are running a race, so they need to be fast. It is a relatively short distance, so runners run very fast in it, so a runner needs to build a high level of speed in order to win. It is the fastest race and shows who can run at the greatest speed.

That means you ran 20 meters in one second, which is about 66 feet per second. This sounds very impossible, but in miles per hour, it was 237,600 mph. (The math: 20 meters=66 feet. 66 feet per second times 60 equal 3960 feet per minute. Times 60 again gives you 237,600 feet per hour. 60 second in a minute, 60 minutes in an hour.) then divide 237,600 feet by 5,320 and the answer is 44.66 mph. There are 5,320 feet in a mile.

ATP-PC system Adenosine triphosphate.- phosphocreatine

phosphocreatine is broken down into phosphate and creatine molecules. as with any bonds that are broken energy is released. The phosphate molecule bonds to ADP (adenosine diphosphate) which produced an ATP molecule. This ATP molecule is used within cells to make energy.
