(a) $30^o$ F (b) $0^o$ F
Use the table to find the "windchill" temperature. (a) $40^o$ F is in the 2nd column while $20$ mph wind is in the 5th row of the first column. The intersection of the 5th row and the 2nd column is $30$. Thus, the "windchill" temperature is $30^o$ F. (b) $20^o$ F is in the 6th column while $35$ mph wind is in the 8th row of the first column. The intersection of the 8th row and the 6th column is $0$. Thus, the "windchill" temperature is $0^o$ F.
