a 12 year old boy can run average of 50kmh fast 12 year olds can go 70kmh when they ran the 100m they ran 12.8

when I was 8 years old I ran then 100m race in 20 seconds now I am 13 and i run it in 12 seconds
I'm 10 as of June 2012 and I run 13.6 in 100m 10.3 in 75m and I'm male
Fast Enough
he can run 100m in 8.3 sec
an 11 year ld can probaly do the 100m in 15 to 16 seconds
Ink it's Around 11 flat or more ideally under that
yes, a 15 year old sprinter with great talent can run 100m in 10.9 and 17 year old could run a 10.5 but these are national winning times and 10.9 for a 15 year old is probably a close to a national record.
