Walking Math
I have a free pedometer app on my phone, and I use it whenever I remember to. A few weeks ago I found my way to the settings page. The stride length default was set at 27″. Mmm… I wonder what mine is? I brought out the measuring tape, laid it down the 15′ hallway, and walked the plank. I did some cipherin’ and ended up at twenty-three inches per each step.
While walking along the Ch’ak Ch’ak trail, there are spray-painted eagles, through a stencil, all along its length. When I start on the Troutdale end there is an eagle right at the start with the key. This is all leading up to “Who’s right?”
This morning I turned on the pedometer at the start and walked until I found the fourth eagle at the mile mark. I was keeping track as I went. At each eagle I’d check what the pedometer read, and it was uniformly accurate. But it wasn’t showing .25 per; it was showing .20 increments. I kept going to see if there was another eagle in another two-tenths of a mile, and there was! Was the key wrong? Was it supposed to have been 1/5? Was my stride length mismeasured? Is the pedometer whacked? Stay tuned.
