For example A-A, B, C, D Correct? If an urgent care clinic is placed in either A, B, C, or D, then citizens in A can get there within 20 mins. B-A.B, D, E C-A, C, D, E, F (Why E? Because 10+ 10 equals 20.) Now, you try to do the rest before going to the next page. FINDING THE ANSWER A-A, B, C, D B-A, B, D, E C-A, C, D, E, F D-A, B, C, D, E, F E-B, C, D, E Where to start? I start with the smallest sets F-C,D,FI G-G, H-H. 1 Obviously, I will have to use either G, H, I, or to get those two sites. . I also see that if I pick D, I can get the first half of the network One answer is 3 sites: D, G, H D covers A-F G covers G . It covers H. I the F-C, D, F, I G-G,J H-HI TJ-GIS Now, do it again, but what if you were trying to ensure everyone could get to an urgent care within 30 mins. . Can you do it with 2 urgent care sites?
