The management of the Dynaco manufacturing plant wants to connect the eight major manufac- turing areas of its plant with a forklift route. Because the construction of such a route will take a considerable amount of plant space and disrupt normal activities, management wants to minimize the total length of the route. The following network shows the distance, in yards, between the manufacturing areas (denoted by nodes 1 through 8): 30 90 70 45 55 2 60 60 50 40 80 6 110 40 160 55 65 Determine the minimal spanning tree forklift route for the plant, and indicate the total yards the route will require.
