Question
At 12:00 PM, the temperature started rising 3°C per hour until it reached 8°C at 3:00 PM. What was the temperature at 12:00 PM?
Solution
To solve this problem, we need to understand that the temperature was rising 3°C per hour.
-
First, we need to find out how many hours passed from 12:00 PM to 3:00 PM. There are 3 hours between these times.
-
Since the temperature was rising 3°C per hour, over 3 hours, the temperature would have risen by 3°C/hour * 3 hours = 9°C.
-
We know that the temperature at 3:00 PM was 8°C. If the temperature had risen by 9°C to reach this, then the temperature at 12:00 PM must have been 8°C - 9°C = -1°C.
So, the temperature at 12:00 PM was -1°C.
