How long would it take for me to walk 3 miles?

Question

I'm in pretty good shape.

I can jog a mile in 7 minutes without trying hard.

I just want to know how long it'd take if I were to casually walk 3 miles.

Answer 1

The average walking speed of a human is only 3 miles per hour.  So it would be about an hour.  

However, if you are jogging a mile in seven minutes I don't think you'll be walking that slow.  I would guess 45 to 50 minutes.

Answer 2

Probably about 30 minutes.  I'm only figuring that because 7x3=21 minutes jogging so casually walking would probably take about 30 minutes...
