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. the hurricane is moving at 15 knots. if it maintains forward speed, how long before tropical storm-force winds begin to affect your community?

We are given that the eye of the storm is 450 nautical miles away and the storm force extends up to 150 nautical miles. So when the eye is 150 miles away from the community, the outer edges of the storm winds will begin to affect the community.

Distance the eye has to travel, d = 450 – 150 = 300 nautical miles

Since t=d/s

where s = 15 knots = 15 nautical mile/hr

t = 300/15

t = 20 hours

the answer will be b
