Question

At 3 o'clock, the temperature was -15°C. The temperature increased by 10°C. What is the new temperature?

A. -5°C
B. -10°C
C. 0°C
D. 5°C

Answer 1

To find the new temperature after an increase, add the temperature change to the initial temperature. Starting at -15°C and increasing by 10°C, the new temperature is -5°C, which is option A.

Step-by-step explanation:

The student is asking about a temperature change in degrees Celsius. We start at -15°C and need to account for an increase of 10°C. The process for calculating the new temperature is to add the temperature increase to the initial temperature. Here is a step-by-step explanation:

1. Identify the initial temperature: -15°C.
2. Identify the change in temperature: an increase of 10°C.
3. Add the temperature change to the initial temperature: -15°C + 10°C = -5°C.

The new temperature after the increase would be -5°C, which corresponds to option A.
