This reminds me that a few years ago I came up with a theory of how seconds came to be. I routinely walk about 45 minutes a day and was curious about how I could calculate distance by counting steps. I counted my steps for a known distance and did the math. I had already determined that my gait was 5 feet per two steps. The math resulted in me realizing that every two steps took me exactly one second. I realized that this may have been how marching armies in ancient times were able to tell how far they had traveled. Consider that marching would result in an averaging of a large group's gait, possibly at my 5 feet per two steps. If someone were to keep track of the number of steps, they could have a fairly accurate estimate of distance traveled. 5 X 60 would be 300 ft (or 100 yds) per minute, a nice round number. Now, I have always wondered about the oddly random-seeming number of feet in a mile. So today I thought, I wonder if 5,280 is divisible by 60? It is! 5,280/60=88!
