PLEASE ANSWER C, D, E . The answer for a is (8.5, 10) if that helps at all.

10.7 A portable lunch wagon is to be located along the main aisle of an industrial plant. On a coordinate system, the main aisle connects the points (0,10) and (12,10). Travel between customer locations and the main aisle is rectilinear. The coordinate points for the locations of workstations served by the lunch wagon are as follows: P1=(2,4); P2=(2,12);P3=(6,4);P4=(6,12);P5=(8,8);P6=(12,12);P7=(10,14);P8 =(12,6);P9=(8,14); and P10=(10,4). a. If a single customer is located at each workstation, where should the lunch wagon be located along the main aisle to minimize cumulative customer walking distance? b. If one customer is located at each of the first five workstations, and three customers are located at each of the last five workstations, where should the lunch wagon be located along the main aisle? c. If it is desired to locate the lunch wagon such that the maximum distance traveled by any customer is minimized, where should the lunch wagon be located? d. Solve (a) by assuming travel must occur along the tree network shown below. e. Solve (b) by assuming travel must occur along the tree network shown below
