Solve the problem.Two LORAN stations are positioned 270 miles apart along a straight shore. A ship records a time difference of 0.00129 seconds between the LORAN signals. (The radio signals travel at 186,000 miles per second.) Where will the ship reach shore if it were to follow the hyperbola corresponding to this time difference? If the ship is 100 miles offshore, what is the position of the ship?
