Question: The wind chill tells you how cold it feels as a function of the air temperature and wind speed. Figure 12.54 is a contour diagram of wind chill (°F).

(a) If the wind speed is 15 mph, what temperature feels like -20°F?

(b) Estimate the wind chill if the temperature is 0°F and the wind speed is 10 mph.

(c) Humans are at extreme risk when the wind chill is below -50°F. If the temperature is -20°F, estimate the wind speed at which extreme risk begins.

(d) If the wind speed is 15 mph and the temperature drops by 20°F, approximately how much colder do you feel?
