APPARENT FAHRENHEIT TEMPERATURES DUE TO WIND-CHILL FACTOR (corresponding to actual temperatures and wind speeds)

At a wind speed of 30 miles per hour, if the actual temperature increases by two degrees Fahrenheit then the apparent temperature increases by approximately how many degrees Fahrenheit?
(A) 5
(B) 7
(C) 10
(D) 15
(E) 20
I don't know if I am correct here or not but, I am assuming that the apparent temperature remains same for every 10F change in Actual temperature!
-10 to 0 = 15F change
0 to 10 = 16F change
10 to 20 = 15F change
20 to 30 = 16F change
So, approximately a change of 15F
Hence, option D?
