Hi

Breaking it up into time intervals

6AM -3�F

9AM -3� + 2�*3 = 3�     |will rise at a rate of 2� per hour for 3 hr

3PM  3� + 3�*6 = 21�    |will rise at a rate of 3� per hour for 6 hr

6PM 21� - 2�*3 = 15�    |will fall at a rate of 2� per hour for 3 hr

8PM 15� - 5�*2 = 5�F    |will fall at a rate of 5� per hour for 2 hr
