Anywhere from 45 to 60 mph. I would say the average would be closer to 60.
I am twelve and I can throw about 70-75 mph. For an average child maybe 80-85 mph.
I'm guessing between 95 & 105 miles per hour
The equivalent of an 80mph pitch from 47ft at 54ft is 54/47*80 = 91.9 mph.
Simple flick the wii remote as fast as you can.
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.
It varies from player to player. Some throw in the 70s to the upper 90s.
However fast the pitcher throws it. In the pros, pitchers, on average, throw a four-seam fastball in the early 90's (mph). A high school senior about 75-80, a 6th grader about 50-60, and a starting player about 20-30. But those are for baseball pitchers, not your everyday person.
As fast as you can throw them ;)
