45-50 secs
start off slow then gradually go faster for more fun ;)
About 16 seconds for a slim semi-fast girl
the average weight is about 80-90 pounds. but some of it depends on how fast you develop
It depends on how much they practice and workout. So anywhere from 45-55 miles an hour.

Well I am 9 years old and I can type about 65 WPM on average and my fastest was 72 WPM, I don't know if that is slow fast or average but saying that it is average a 11 year old girl should type about 80 - 100WPM.
