The given equation is already formulated for you. The boundaries for this equation is between 5 to 30 miles per hour. Since the wind speed is 20 miles per hour, you can use this equation. Just substitute w = 20 to wind C.

C (20) = 0.013 (20) ² - 20 - 7

C = - 21.8 F

Hence, the chill temperature is - 21.8 degrees Fahrenheit when the wind speed is 20 mph.
