The eye of a hurricane passes over Grand Bahama Island. It is moving in a direction 60.0° north of west with a speed of v1 = 42.0 km/h. Exactly three hours later, the course of the hurricane shifts due north, and its speed slows to v2 = 24.0 km/h, as shown in Figure 3-30. How far from Grand Bahama, in kilometers, is the hurricane 4.50 h after it passes over the island?
