Question

"The temperature this morning was -3°C, and by noon, it had risen 8°C. What was the temperature at noon?"

A. 3°C
B. -8°C
C. 5°C
D. -11°C

Answer 1

The temperature at noon was 5°C, calculated by adding the 8°C rise to the morning temperature of -3°C.

Step-by-step explanation:

The student's question involves calculating the temperature at noon given that the temperature in the morning was -3°C and it had risen by 8°C by noon. To find the temperature at noon, we add the temperature increase to the morning temperature.

So, starting with -3°C and increasing by 8°C gives us:

-3°C + 8°C = 5°C.

Therefore, the temperature at noon was 5°C. Generally, temperatures tend to rise during the day due to the sun's position in the sky, reaching a peak in the afternoon, then cooling off as the evening approaches. However, there are many factors that can influence these changes, including weather patterns, seasons, and geographical location.
