Given the statement:
At midnight, the temperature is 34 degrees Fahrenheit. The temperature decreases 2 degrees each hour until 3:00 A.M. The temperature then increases 3 degrees each hour until 7:00 A.M
Determine the temperature at 7:00 A.M.
Solution:
This can be done manually by subtracting and adding based on the given conditions.
Temperature decreases by 2° each hour until 3:00 A.M.
12:00 AM = 34°F
1:00 AM = 32°F
2:00 AM = 30°F
3:00 AM = 28°F
Temperature increases by 3 degrees each hour until 7:00 A.M.
4:00 AM = 31°F
5:00 AM = 34°F
6:00 AM = 37°F
7:00 AM = 40°F
Final answer:
The temperature at 7:00 AM is 40°F
