2. The position of the ship at 10:04 is (-5.2, 0). The position of the ship at 10:40 is (0, 9.7798). Calculate the distance traveled during these 36 minutes to get the speed of the ship in .
3. Calculate the distance traveled during the time from 10:04 to 11:10. With this distance and the known angle you can determine the position of the ship.
4. Use the Cosine law to determine the position where radio contact isn't possible.
