~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


        The solution in the post by  @consc198  is  FATALLY  WRONG,
        since  @consc198  did not take a labor to read the problem and to think on its meaning.

        For a correct solution see what follows. 


The time interval from 2:00 AM to 3:00 PM is 13 hours.


Therefore, the hourly rate of the temperature change this day is (based on given data)

    %2856-43%29%2F13 = 13%2F13 = 1 degree Fahrenheit per hour.

Solved correctly.
