Given the Following Process Layout Data for Locating Four Departments

Given the following process layout data for locating four departments (A, B, C, and D) in four areas (1, 2, 3, and 4): $\begin{array}{l}\text { Distances (meters) } \quad\quad\quad\quad\quad\quad \text { Flows (loads per week }\\\begin{array}{rlll}\text { From/To } & 1 & 2 & 3 & 4 \\\hline 1 & - & 50 & 100 & 150 \\2 & & - & 50 & 100 \\3 & & & - & 50 \\4 & & & & -\end{array}\quad\quad\begin{array}{rlll}\text { From/To } & \text { A } & \text { B } & \text { C } & \text { D } \\\hline \text { A } & - & 10 & 40 & 50 \\\text { B } & 30 & - & 10 & 70 \\\text { C } & 60 & 10 & - & 40 \\\text { D } & 30 & 50 & 20 & -\end{array}\end{array}$ If department C must be located in area 1, what layout will minimize the total distance loads will be moved each month?
