About thirteen to fourteen seconds if you are referring to track
11seconds
14. 56 is a good time
To me a good time would be 14-15 seconds.
a 11.9 and lower is a good time
like time passing? try 100 years by five for fighting
11.8 - 12.4 seconds
yes but try to get faster
Any time under 40 seconds is a good time for the 300 Meter Intermediate Hurdles for high school boys.
11-12 seconds
If you are in the age between , 12-16 that is a very good time
100 to a 150 thousand miles is a good time
Around 13 seconds
