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).
Determine how fast you walk. If you do not know, then use the average speed of three miles per hour. In the example, use a speed of three miles per hour. Divide the distance by the speed. For example, two miles divided by three miles per hour equals 0.667 hours, which is approximately 40 minutes.
