Question
The equation above expresses the temperature C, in degrees Celsius, in terms of the temperature R, in degrees Rankine. Which of the following expresses the temperature in degrees Rankine in terms of the temperature in degrees Celsius?
The correct answer is:
C = 
(R - 491.67)
9C = 5(R - 491.67)
= R - 491.67
R = + 491.67.
