Florence Griffith-Joyner holds the women's world record in the 100 meter dash at 10.49 set in 1988.Florence Griffith-Joyner is the fastest female 100 m runner in the world. She set the record of 10.49 seconds on July 16, 1988.
11.99 seconds because 100 yard dash is 91 meters. 100 meters/91 meters = 1.09 Then do 11 seconds x 1.09 = 11.99 seconds. If you round it, you basically be getting a 12 second 100 meter dash.
7.2 seconds in the 55 meters converts to 4.788 seconds in the 40-yard dash.
