A pipe must be buried underground to reach from a station on the shoreline to an outpost that is 5 miles down the shoreline and 2 miles into the ocean from the shoreline. It costs 3 times more per mile to bury the pipe under the ocean floor than it does to bury thepipe along the shoreline. How far along the shore should the pipe be buried before turningtowards the outpost if the goal is to minimize the cost?
