Answer
(a) $-17^o$ F
(b) $-41^o$ F
Work Step by Step
Use the table to find the "windchill" temperature.
(a)
$5^o$ F is in the 9th column while $25$ mph wind is in the 6th row of the first column.
The intersection of the 6th row and the 9th column is $-17$.
Thus, the "windchill" temperature is $-17^o$ F.
(b)
$-5^o$ F is in the 12th column while $35$ mph wind is in the 8th row of the first column.
The intersection of the 8th row and the 12th column is $-41$.
Thus, the "windchill" temperature is $-41^o$ F.
