A resort is situated on an island that lies exactly 4 miles from P, the closest point to the island along a perfectly straight shoreline. 10 miles down the shoreline from P is the nearest source of water. If it costs 1.6 times as much money to lay pipe in the water as it does on land, how far down the shoreline from P should the pipe from the island reach land with minimum total constructions costs?
