For men running under a 60seconds would be good for a 12 year old. Towards the end of High school for an 18 year old a good time would be about 48seconds. And College should range from 44-47 for a good 400m.
14. 56 is a good time
Around 13 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.
depending on how fast you can run i'd say 3:00-3:30
its alright
a 11.9 and lower is a good time
no...
You're good if you are 14, 5'7" and 138 lbs., and can run the 40 yard dash in 4'72 and the 100 meter in 12 seconds.

If there were sports for animals a Cheetah would be good at the 100 meter dash.
