An island community that has been living without elecric power has decided to have
electricy brought to the island. The elecric lines must be brought from the nearest
town to the island. The island is 5 miles from the nearest point of the shore. The town is located on the shore and is 13 miles from the point on the shore that is nearest
to the island.
The community is considering how to run the cables. It costs 50% more to run the cable under the water than it does to run under the ground. How far should the cable be run along the shore so that the community will have to pay the smallest amount possible?
