Essay

Exhibit 5-3
Steve the auto parts salesman is trying to navigate his way between the rural west Texas towns of Jonestown and Upland. The possible routes for this trip are shown below, along with the mileage along each route.
$\begin{array}{lrcc}\text { Origin } & & \text { Destination } & \text { Distance (miles) } \\\text { Jonestown } & \text { to } & \text { Haleyville } & 25 \\\text { Jonestown } & \text { to } & \text { Krickburg } & 55 \\\text { Jonestown } & \text { to } & \text { Karn City } & 35 \\\text { Haleyville } & \text { to } & \text { Mart } & 50 \\\text { Haleyville } & \text { to } & \text { Krickburg } & 25 \\\text { Haleyville } & \text { to } & \text { Karn City } & 30 \\\text { Karn City } & \text { to } & \text { Mart } & 50 \\\text { Karn City } & \text { to } & \text { Baker } & 65 \\\text { Krickburg } & \text { to } & \text { Karn City } & 20 \\\text { Krickburg } & \text { to } & \text { Baker } & 30 \\\text { Krickburg } & \text { to } & \text { Mart } & 45 \\\text { Mart } & \text { to } & \text { Baker } & 20 \\\text { Mart } & \text { to } & \text { Upland } & 40 \\\text { Baker } & \text { to } & \text { Upland } & 30\end{array}$
-Refer to Exhibit 5-3.Suppose the roads leading into and out of Krickburg are unpaved,so Steve would only be able to travel half of his usual 60 mile/hour speed on those routes.Modify the model to account for this condition.Would the shortest path change from the base case solution
