Humans walk at an average speed of between 3 to 4 miles per hour.
So if you were to walk an hour you would cover at least 3 to 4 miles in that one hour of walking depending on your walking speed.
Walking slower will take longer to cover the same amount of miles than walking faster.
I remember breaking down in my car 5 miles from home and was on a back road where no help was available and I had no cell phone signal.
So I had to walk home.
With some breaks it took me 1 hour and 45 minutes to walk the 5 miles home.
It was good exercise but my legs and feet hurt.
My husband went back and got the car with his trailer.
