well it depends if they are good or not, the average speed of a 13 year old that isn't that athletic and dosent play like juniors or club ball is probably 45 mph the AVERAGE speed of a 13yr old in junior league is probably about 60-65 mph well I'm 13 5'8 130 pounds and i can get up to 72 mph. My dad says that good but it depends.
I am twelve and I can throw about 70-75 mph. For an average child maybe 80-85 mph.
The average 10 yr old kid throws the ball 45MPH. About 33% of pitchers this age can throw the ball 45-50MPH and about 13% can throw the ball 51-55. About 1 kid in a million can throw the ball 60MPH. If your kid can throw more then 48MPH he is considered above average.
the average 13 year old throws about 65 to 70 miles an hour. there are some boys that can throw harder though (:

I am 14 years old. And I can run about 20 mph. But I run every day, the average is about 14 - 16.
It shoud be 60-75 miles per hour. A good 13 year old should be in the low to mid 50's. An average 13 year old is in the mid 40's.
An average 7 year old can throw from 30 to 40 mph. A 7 year old that is a freak and stand out and one of the best on the best of team can throw 45 and top out at 50 max.
