15 t0 20ish
A 12 year old's average time for the 100 meter dash, should be about 15 or 16 seconds.
17.22
As a 100 yard dash sprinter in the 60's the average time would be about 10.2 to 10.3.
20 seconds -- if they are relatively fit. Otherwise, I'd say an average 60-year old wouldn't even make it that far.
its usually 8-9 seconds
An average time for a 14-year-old running the 50 meter dash is around 9 seconds. For a 100 meter dash, it would be about 13 seconds.
Any time between 15 and 17 seconds is decent :]! Im 13 and I run the 100 between 13 and 14!
13.25 seconds
14.00-16.00 seconds
