'Cartouche' is actually a French word meaning 'gun cartridge'. When Napoleon's soldiers were in Egypt, they nicknamed this shape 'cartouche' because it reminded them of the shape of their gun cartridges, or bullets. At the time, people could not read hieroglyphic writing, so they did not know that the cartouche surrounded the name of the pharaoh. 'Cartouche' became so commonly used that it has remained the standard name for the shape around the name of an Egyptian pharaoh or queen. Were royal names always written inside cartouches? In the first three dynasties, royal names were written inside a rectangle called a 'serekh'.
Maximum Speed. The maximum swimming speed for humans is approximately 2 meters per second, or approximately 4.5 miles per hour, Dutch researchers Huub Toussaint and Martin Truijens reported in the journal Animal Biology in 2005 â only 16 percent of the maximum land speeds of elite human sprinters.
How Fast Can Humans Run? The average human walking speed is in the neighborhood of 3 mph (4.8 km/h). How fast do you think you could run at a full sprint? 10 mph? 15 mph? What speed could you average over 26.2 miles? Below, I have taken several men's and women's world records and calculated the runners' average speed. Usain Bolt has averaged over 23 miles per hour in both the 100 and 200 meter events. It's interesting to note that the 60 meter race has a slower average speed for both men and women than the 100 meter race. This must be because accelerating at the start of a race takes some time. These world records were last updated on October 30, 2015.
