![A cruise ship maintains a speed of 14 knots (nautical miles per hour) sailing from San Juan to Barbados, a distance of 600 nautical miles. To avoid a tropical storm, the captain heads out of San Juan at a direction of 19° off a direct heading to Barbados. The captain maintains the 14-knot speed for 15 hours, after which time the path to Barbados becomes clear of storms.
(a) Through what angle should the captain turn to head directly to Barbados?
(b) Once the turn is made, how long will it be before the ship reaches Barbados if the same 14-knot speed is maintained?
(a) The captain should head through an angle of 28.7°.
