A freshwater pipeline is to be run from a source on the edge of a lake to a community on an island 5 miles offshore, as shown in the figure. Answer the questions that follow. Island 5 miles X 15-x 15 miles. Source (A) If it costs 1.5 times as much to lay pipe in the lake as it does on land, what should x be (in miles) to minimize the total cost of this project? X = miles (Round to the nearest tenth as needed.)
