The eye of a category 2 hurricane is 450 nautical miles away and forecast to come ashore at your coastal location. the tropical storm-force winds extend 150 nautical miles. if the hurricane's forward speed is 20 knots, how long before tropical storm-force winds begin to affect your community?

30 hours

Explanation:

Total distance from the coast to the storm = 450+150 = 600 Nmi

Speed of the hurricane = 20 knots = 20 Nmi/h

Time taken by the hurricane to reach the coast

∴ Tropical storm-force winds begin to affect the community by 30 hours

Time taken by the eye to reach the coast

\text{Time}=\frac{450}{30}=15 hours[/tex]
