You decide to estimate the distance of distributing the notebooks from a DC in one of a set of selected cities to the school children in another city. Given that you only need a quick and dirty estimate, you assume a Euclidean space and a circuity factor of 1.25, which gives you the distances in the table below.

Regardless of which city the DC is located in, there will also be transportation from the DC to the school children within that same city. For distances inside each city, you assume 5 distance units, except for Mexico City, for which you use 10 distance units since it is a larger city.
