9.70 - 9.80 seconds.

15 seconds would probably be good for a 10 year old, or maybe in the 14s.

I just turned 13, I'm a little bit faster than average and I got 6.35. But the 40m sprint is completely irrelevent to 100m cause I got 15.72 in the 100m and my friend (who got 6.39 in the 40m) got 14.96. So the 40m sprint is just about accelaration not speed.

It depends on the child. If hes fast or slow. If you average 15 mph in a 100m sprint then your time will be 14.91 seconds. That's pretty impressive if a 5 year old can run that fast.
it was shelly an fraser she won with 10.78 sec.
The current world record for the men's 100m sprint is 9.58 seconds, set by Usain Bolt of Jamaica in 2009 at the World Athletics Championships in Berlin, Germany. Bolt is widely considered one of the greatest sprinters of all time.
Sprint the 100m but do it with resistance, for example a parachute or weighted vest. Also make sure that you get completely stretched out before you time it, including your arms.
