The temperature at noon was 88F by 4pm the temperature was 72F. Find the rate of change

The rate of change would be 23F because if you can see the paradigm of the time equionix you would see that if you divide 10 by infinity and you got the coordinates of the center of the earth divided by the miles of earth to the sun you would get the inpenetrable response of the human bloodline reaction of the center of the earth and the global warming economy of the united states congress

I think that the answer would be 88F - 72F (the difference) so the answer would most probably be 16
