14.0-14.5 seconds, by ninth grade you should look to be at 12.9 to be competetive.
About 16 seconds for a slim semi-fast girl
I do not know. But when i was twelve, I ran a 100meter dash in about 12, 13 seconds. Is that good?
A time of 15.1 seconds in the 100 meters for a 12 year old is a good time. It is not considered especially fast, but it is likely as fast or faster than average.
You have to multiply the number of meters by 100.
faster than me
