The average walking speed of a human is approximately 3 to 4 miles per hour (4.8 to 6.4 kilometers per hour). This speed can vary based on factors such as age, fitness level, terrain, and purpose of walking. Younger and fitter individuals tend to walk faster, while older adults or children may walk more slowly. Walking speed also decreases on uneven or uphill surfaces and increases on flat, smooth paths. For casual strolling, speeds are often closer to 2-3 mph, while brisk walking for exercise may reach 4-5 mph. Walking speed is a useful measure for estimating travel times on foot.
