A boat leaves port and follows a course of N77E at 9 knots for 3 hr and 20 min. Then, the boat changes to a new course of S26E at 12 knots for 5 hr. Part 1 of 3 (a) How far is the boat from port? Round the answer to one decimal place if necessary. (b) Suppose that the boat becomes disabled. How long will it take a rescue boat to arrive if the boat leaves from port and travels 18 knots? Round to the nearest minute. The rescue boat will arrive in approximately 4 hr 0 min. x 5 A fishing boat leaves a marina and follows a course of S62W at 6 knots for 20 min. Then the boat changes to a new course of S39W at 4 knots for 1 hr. Round intermediate steps to four decimal places. Part 1 of 2 (a) How far is the boat from the marina? Round the answer to one decimal place if necessary. The boat is approximately 5.9 nmi from the marina. Part: 1/2 Part 2 of 2 (b) What course should the boat follow for its return trip straight back to the marina? Round the answer to one decimal place if necessary. The boat should follow the course (Choose one) (Choose one) N S X G W E Two boats leave a marina at the same time. The first boat travels 8 knots at a bearing of N22E, and the second boat travels 3 knots at a bearing of S83W. Part 1 of 2 (a) How far apart are the boats at the end of 5 hr? Round to the nearest tenth. The boats are approximately 49.1 nmi apart. Part: 1/2 Part 2 of 2 (b) What is the bearing from the first boat to the second boat at that time? Round to the nearest tenth. The bearing is (Choose one) O (Choose one) X G L A boat leaves port and follows a course of N77E at 9 knots for 3 hr and 20 min. Then, the boat changes to a new course of S26E at 12 knots for 5 hr.
