In the following diagram,Srepresents the position of a power relay station located on a straight coast, andEshows the location of a marine biology experimental station on an island. A cable is to be laid connecting the relay station with the experimental station. If the cost of running the cable on land is$1.50/running foot and the cost of running the cable under water is$2.70/running foot, locate the pointPthat will result in a minimum cost (solve forx). (Round your answer to the nearest whole number.)

What does x=? (in feet)
