Running the 100-meter dash in 12.7 seconds is the same as running the 40-yard dash in 4.645 seconds.
Approximately 8 seconds
14 seconds was the record set by me
It would be fast if run by a boy younger than 10 or a girl younger than 12.
Your pace is 17.61 mph
about 12-15 seconds
faster than a chicken that's for sure
