A Formula Used by Meteorologists to Calculate the Wind Chill

question 1

Multiple Choice

A formula used by meteorologists to calculate the wind chill temperature (the temperature that you feel in still air that is the same as the actual temperature when the presence of wind is taken into consideration) is ​ ​
Where t is the actual air temperature in °F and S is the wind speed in mph.
​
What is the wind chill temperature when the actual air temperature is 40 °F and the wind speed is 15 mph (T​₁) ? Please round the answer to the nearest °F
​
If the temperature is 40 °F, by how much approximately will the wind chill temperature change if the wind speed increases from 15 mph to 16 mph (T​₂) ? Please round the answer to the nearest tenth.
