For the tree shown in Figure 6.32

(a) Find the 1-median. Clearly indicate where the solution is.

(b) What is the objective function for the 1-median problem?

(c) By how much would the demand at node F have to increase for the location of the 1-median to change? Where would the new 1-median be located?
