13 - 13.5 seconds
That's a fair time.
9.58s for men and 10.49s for women.
11.25 seconds
To convert a time in a 100m dash to miles per hour (mph), you can use the formula: mph = 3600 / (time in seconds). If the time in the 100m dash is 13.00 seconds, then the calculation would be: 3600 / 13.00 = 276.92 mph.
Usain Bolt with 9.58s
Three seconds on the 100m dash!
around 30 seconds
Florence Griffiths-Joyner with 10.49s.
I do 14:89 but 15 or 16 seconds is also good
14. 56 is a good time
9.57 was mine
