Bacon has an ancient history. The domestication of pigs (immature hogs) for food dates back to about 7000 B.C. in the Middle East. Some historians say that bacon made from hogs was a favorite of the early Romans and Greeks. About 500 years ago, bacon or bacoun (a Middle English term) referred to all pork.
Although walking speeds can vary greatly depending on many factors such as height, weight, age, terrain, surface, load, culture, effort, and fitness, the average human walking speed is about 5.0 kilometres per hour (km/h), or about 3.1 miles per hour (mph).
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.
