The temperature adjusted for wind-chill is a temperature which tells you how cold it feels, as a result of the combination of wind and temperature.

Temperature (F)

35 30 25 20 15 10 5 0

5 31 25 19 13 7 - 1 - 5 - 11

10 27 21 15 9 31 - 41 - 10 - 16 Wind Speed (mph)

15 25 19 13 6 0 - 7 - 13 - 19

20 24 17 11 4 - 2 - 9 - 15 - 22

25 23 16 9 3 - 4 - 11 - 17 - 24

(a) If the temperature is 0°F and the wind speed is 10 mph, how cold does it feel?

(b) If the temperature is 35°F, what wind speed makes it feel like 25°F?

(c) If the wind is blowing at 10 mph, approximately what temperature feels like 0°F?

a. - 16°F

b. 15mph

c. a=12.5F

Step-by-step explanation:

Wind speed temperature

35 30 25 20 15 10 5 0

5 31 25 19 13 7 - 1 - 5 - 11

10 27 21 15 9 3 - 4 - 10 - 16

15 25 19 13 6 0 - 7 - 13 - 19

20 24 17 11 4 - 2 - 9 - 15 - 22

25 23 16 9 3 - 4 - 11 - 17 - 24

going by the table above we interpolate from left to right, to get the corresponding value. where mph meets with the tem[erature in the column is what the temperature feels like

(a) If the temperature is 0°F and the wind speed is 10 mph, how cold does it feel?

ans - 16°F

b. If the temperature is 35°F, what wind speed makes it feel like 25°F?

answer 15mph

c (c) If the wind is blowing at 10 mph, approximately what temperature feels like 0°F?

Form difference quotient across the row starting at position (10, 30):

is 6/5

6/5 = (0-3) / a-15

a=12.5F
