Problem Solving SEERVADA PARK has recently been set aside for a limited amount of sightseeing and backpack hiking. Cars are not allowed into the park, but there is a narrow, winding road system for trams and for jeeps driven by the park rangers. This road system is shown bellow where location O is the entrance into the park; other letters designate the locations of ranger stations (and other limited facilities). The numbers give the distances of these winding roads in miles. The park contains a scenic wonder at station T. A small number of trams are used to transport sightseers from the park entrance to station T and back. The park management currently faces a problems: is to determine which route from the park entrance to station T has the smallest total distance for the operation of the trams. Use the shortest-route technique to minimize total distance from the park entrance to station T. A 2 2 7 5 T 5 4 B D 7 3 E 4
