the problem says:
one day, the temperature at 2:00AM was 44 degrees farenheiht , and by 2:00PM the temperature was 68 degrees farenheit. WHat was the hourly rate of temperature change?

the possible answers are to pick from

(a) 1 f/h
(b) 2 f/h
(c) 3f/h
(d) 4f/h

but when i solved it this is what i did and what i got.

68-44 = 24
then i divided the (24)/(15hs)= 1.6

but i don't know should i round up or stay at 1

how did you get 15 hours? 2PM - 2AM = 12 hours.

24 degrees / 12 hours = 2 degrees/hr

your absolutely right i counted wrong...thank you
