Deuteronomy 1:2

"It is eleven days' journey from Horeb by the way of mount Seir unto Kadesh-barnea."

"Days' journey ..." Distances were counted by the time required to travel. "A day's journey was about twenty miles if one traveled on foot, or thirty miles (at three miles and hour) by camel, and twenty-five miles by caravan."[6] It appears very likely, however, that a great company like Israel would not have been able to move as rapidly as a smaller company might have traveled. The actual distance indicated here was only about 100 miles.
