If you ran 9.84 sec in the 100m with a head wind of 0.05 sec how fast would you ran if there was no wind?

Effective distance run = 100 m + (9.84 x 0.5) = 104.92

Effective speed = 104.92 m per 9.84 s

Therefore with no wind resistance, time to cover 100 meters = 100/104.92 x 9.84 = 9.3786 (9.38) seconds.
