the Administration Department of a Small College Is Now

Table 9.9
The administration department of a small college is now designing its layout for newly built office space. From statistical samplings over the last three months, the following trip matrix was developed for daily trips between departments.
Trip Matrix (trips/day)
$$\begin{array} { | c | c | c | c | c | c | c | } \hline & \mathrm { A } & \mathrm { B } & \mathrm { C } & \mathrm { D } & \mathrm { E } & \mathrm { F } \\\hline \mathrm { A } & - & 10 & 75 & & & 140 \\\mathrm {~B} & & - & & & 95 & \\\mathrm { C } & & & - & & 130 & 130 \\\mathrm { D } & & & & - & 10 & \\\mathrm { E } & & & & & - & 95 \\\mathrm {~F} & & & & & & - \\\hline\end{array}$$
-Use the information in Table 9.9.One block plan suggested for the department looks as follows:
$$\begin{array} { | c | c | c | } \hline \mathrm { C } & \mathrm { F } & \mathrm { A } \\\hline \mathrm { B } & \mathrm { E } & \mathrm { D } \\\hline\end{array}$$
What is the total load-distance score of this plan using rectilinear distance and assuming departments A and B are 3 units of distance apart?

A) less than 800
B) more than 800 and less than 850
C) more than 850 and less than 900
D) more than 900
