More bicycling....

On a ride today I came up with an interesting idea. For example, I completed a ride that was 20 miles and my average was 13 mph. I decide to complete the ride again a couple of days later and my average increases. Well, I get to thinking that when I do this ride again what will happen to my average. So I attempt the ride again, trying to keep the variables somewhat consistent. After doing this a number of times I graphed my results. Guess what? It wasn't what I was thinking. I thought it might be a negative quadratic. Not really. Just a line of best fit.

Just a plug. Yes it Desmos.

Here's a table with the graph.

I just think it is cool that math can evolve from just a thought.
