The world record for the hundred meter dash is 9.58 seconds, which corresponds to an average speed of 10.44 m/s. To convert this to other units of speed: 10.44 m/s=0.01044km/(1/3600)h= 37.58 km/h 10.44 m/s=(10.44 x 3.281 ft)/s is equal to 34.25 ft/s 10.44 m/s=(10.44/1609.344)/(1/3600)=23.35 mi/h 1 meter is equal to 1.094 yards, so 100 meters is equal to 109.4 yards To run 109.4 yards at an average speed of 10.44 m/s, it would take 10.44 seconds.
