Bill is concerned about the frostbite risk for workers clearing snow. The weather report predicts the air temperature will be -15 degrees Fahrenheit.
Joe comes up with an equation relating air temperatures caused by the wind and wind speed: y =- 5/ 3 x-38.3
where x is the temperature adjusted for wind speed (in degrees Fahrenheit) and y is the wind speed (in mph).
What is the wind speed, if the temperature adjusted for wind speed is -38 degrees Fahrenheit?
2 answers
just substitute -38 for x and simplify the result.
Thank you
