Yes, that is very good for a 12 year old while a man in the Olympics can run about 9 seconds for 100 meters.
No it is not but for a 13 year old it would be.
i would say a good 100m time for a 10 year old boy is around 16-17secs. I am an 11 year old girl and ran the 100m in 15.9 secs.
What is the new time that Bolt ran for 100-meters
no i am six and blind but I can do it in three seconds
11.8 - 12.4 seconds
If you maintain that same pace for the whole 100 meters, your time will be 13.12 seconds in the 100 meters.
A 9.6 second time in the 100 yard dash is the same as running the 100 meters in 10.5 seconds.
1 minute 20 seconds atleast
A time of 15.1 seconds in the 100 meters for a 12 year old is a good time. It is not considered especially fast, but it is likely as fast or faster than average.
