I'm a 13 year old boy and I run 100m in 11.69. But I've raced some kids at my track meets who are a lot faster than that. They probably run like a 10.8! I've seen the times too really fast. So I'd say a good time is around 10-12
fast.
i would say 75mph 80mph for a good pitcher
8 minutes
Between 55 and 75 MPH
Should pitch at least 75 at high 80
about 6-8 seconds
about 60 seconds.
faster than me
A 10 year old girl should pitch about 40-55mph.
You should probably take her to the vet and have them put her to sleep. It would be fast and painless.
It's mostly teenager who start, but it's NOT a smart idea.
15 mph sprinting full speed is average for a 10 year old. Also, a 10 year old to run a mile in 9 min and 45 sec running as fast as they can.
