Answer 1

Step-by-step explanation:

The first person timed at under ten seconds was Bob Hayes, who ran 9.9 s in April 1963 at the Mt. SAC Relays, but with a tailwind of 11 mph (4.9 m/s). Hayes clocked another illegal 9.9 s (wind 5.3 m/s (12 mph)) in the semi-final of the 1964 Olympic 100 m, with the first sub-10 FAT of 9.91 s.
