Q:

# How long does it take to walk 400 meters?

A:

Walking speed varies based on age, health, height, weight, culture and effort. However, a 1996 study from the Transportation Research Board found that the average walking speed of an adult human is approximately 3.1 mph, and, at this rate, a person covers 400 meters in about 4 minutes.

Dominant theories point to walking as a trait of human beings as early as 1.5 million years ago. Footprints discovered on an ancient beach in modern-day Kenya indicate that ancestors of Homo sapiens engaged in familiar two-legged locomotion, which freed the hands for other uses and contributed to the rapid advancement of early humans.
