Around 5 centuries, so I would not bother starting.
20/4 = 5 hours
At a brisk pace (4 miles per hour) it would take 1 hour and 15 minutes.
(3.5)/(2.5) = 35/25 = 7/5 = 1 and 2/5 hours
It depends on what size steps you take and what speed you go. If you decide to walk very slowly it will take a lot longer than if you walk fast.
If you walk an average of 5 mph then it will take you 15 hours
If you were to walk 5 miles per hour, it would take you 2 hours and 10 minutes.
90 minutes
5 / 6 * 60 minutes ....
36 minutes.
5 hours
9 minutes 22 seconds.
Depends entirely on how fast you walk. I would do it in roughly 3 minutes.
