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.
To give some context for all of the above, the fastest-ever recorded speed for a human being was when Usain Bolt ran the 100-meter dash in 9.58 seconds, reaching a top speed of 44.72 km/hr or 27.78 mph.
