Suppose the temperature at 12:00 noon is increasing at an (instantaneous)
degrees F. per hour. What is the rate of change of the temperature
in degrees C. per hour.
Hint: The relationship between degrees F. and degrees C. is linear,
zero (0) degrees C
equals 32 degrees F, and 100 degrees C equals 212 degrees F.
The rate of change in degrees C per hour is
rate= 3F/hr= 3(5/9) C/hr
