a fast time is around 35sec or less but that is at state/national level normally 45 and under ur doing great but 35sec and under is bloody brill
someone has done it 31 secs
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.
that's freaky fast
5 meters per year
faster than me
How fast it runs depends on its width and depth and time of year.
"Meters per second" is a proper and wonderful unit for speed, but there's no answer to that question, because a 'light-year' is not a speed. It's a distance, defined as the distance that light travels through vacuum in one year. Speed of light in vacuum . . . 299,792,458 meters per second Length of 1 light-year . . . . . 9.4605284 × 1015 meters
65sec
About 16 seconds for a slim semi-fast girl
I do not know. But when i was twelve, I ran a 100meter dash in about 12, 13 seconds. Is that good?
A metre is a unit of distance. A year is a unit of time. The two units are therefore incompatible.
Depends on which bit of coast you mean. Some is fast some is slow and some actually grows.
