As part of the male reproductive system, the prostate glandâs main purpose is to secrete a slightly alkaline fluid that forms part of the seminal fluid, a fluid that carries sperm.
Average Speed. If you take the average speed of the current world 100 m record (Bolt's 9.58 s), you get about 10.44 meters/sec (23.35 miles/hr, 37.58 km/hr). However, if you were to record instantaneous speed at different points throughout the race, the runner would reach a maximum speed much greater than this.
Usain Bolt also holds the record for the fastest 100 metres with a running start at 8.70 (41 km/h). This was achieved during a 150 metres race in Manchester 2009, completed in 14.35 (also a World Record).
