The weather service is tracking Hurricane Jeffery on a grid map with coordinate units representing 10 miles. At 10:00 a.m., the center of the hurricane is located at (3, -4). Hurricane-force winds extend 70 miles out from the center. It is predicted that the eye of Jeffrey will be located at (-1, -2) in two hours. Your cabin by Lake Helen is located on the grid map at (-7, -5). Will you feel the force of the hurricane winds at noon? What is the predicted rate (in miles per hour) of the movement of the eye of Jeffrey?
To find if I would feel the hurricane winds at noon, do I find the square root of,
[-10-(-70)]^2 + [(-20-(-50)]^2 ?
How would I find the "predicted rate (in miles per hour) of the movement of the eye of Jeffrey?"
