Avoiding a Tropical Storm A cruise ship maintains an average speed of 15 knots in going from San Juan, Puerto Rico, to Barbados, West Indies, a distance of 600 nautical miles. To avoid a tropical storm, the captain heads out of San Juan in a direction of off a direct heading to Barbados. The captain maintains the 15-knot speed for 10 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 15-knot speed is maintained?
