The temperature changed by -2 degrees F per hour from noon on Tuesday until 10:00 AM the following morning. The temperature at 8 PM on Tuesday was 49F.
What was the temperature at 4:00 PM on Tuesday?
What was the temperature at 12:00 PM on Tuesday?
When was the temperature 30o F?

At 4:00 pm it was 31 F so at 3:30 it's at 30 F and at 12:00 it would be 23 F

Step-by-step explanation:

8 - 4 = 4pm

2 * 4 = 8 degrees

49 - 8 = 31 F

2 - 1 = 1 which is a half so 60 min divided by 1/2 is 30 so take 4:00 - 30min is 3:30

4pm to 12pm in time is 4

2 * 4 = 8

31 - 8 = 23 F

At 4:00 pm it 31 F  at 3:30 it at 30 F and at 12:00 it will be 23 F
