This is what happens when you put two scientists in a room together

We have a new staff member starting at work soon. He is looking for an apartment. Another colleague recently went through a series of apartments looking for one that he found accessible and I suggested he might be able to share some of what he learned. We got into this discussion and it came up that it seemed the farther you get from campus, the better the apartments became. Somehow, paper and a pencil was involved and this sketch happened:

I think the fact that the "optimum distance to campus" is given in metric units just ices the cake.
