From home to work and home again

The average human has to go 15 miles to get to work and 15 back. So that would mean that it would take 30 miles a day to go to and from work. And in a week it would take over 150 miles to go to and from work. but to go and visit friends and family it could take up an extra 30 to 40 miles a day so altogether it would take about 180 miles a week.
