Answer
Donovan Bailey's top speed was 27.1 mph. This is a relatively slow speed for a world-class sprinter, as Bailey's world record time of 9.84 seconds for the 100-meter dash equates to a speed of approximately 23.3 mph. Bailey's top speed of 27.1 mph was likely achieved over a shorter distance, such as the first 10 or 20 meters of a race.
