23.1958mph is an average speed, which includes reaction time, and time required to attain top speed. To find a sprinter's top speed, you need to look at 10m splits. Usain Bolt ran a .81s 10m split in 2009, which means his top speed was 27.77mph (44.4kph)

100 meters/9.7 seconds = 23.0612 miles per hour (rounded)

To convert the time to miles per hour, first convert 100 meters to miles (0.0621371 miles). Then, divide that distance by the time in hours (10.92 seconds = 0.0030333 hours). Finally, calculate the speed by dividing the distance in miles by the time in hours to get approximately 20.44 mph.
