It depends on how fast the kid naturally runs. If they run really fast, it might be a 60 second half mile. If they run slow, it might be a 2-3 minute mile
Breeds determine how fast they run, there's no such thing as an "average dog". A more specific answer would be.. Example Question: How fast does the average (specific kind of breed) run?
around 19 knots
im 12 and i run it in about 14.52 second
They run at least 15 mph
How about "could"? For example, "I could run fast when I was a kid."
Average person - 6mph.
up to 25mph
An average speed of typing for a kid could probably be typing a letter each second. I learned how to type fast without looking at the keyboard when I was very little. Until now, I still type fast and I use it. I like to type fast!
