Question

Morgan read the thermometer at 7 PM. The temperature was 16 Celsius this temperature was nine Celsius less than the temperature at 2 PM. The temperature at 2 PM was 10 Celsius higher than the temperature at 8 AM. What will the temperature at eight

Answer 1

Answer: 15°C

Explanation:

To solve this, it is easiest to create a list of what we know and what we are trying to find and assign useful variables that might make the problem more efficient.

At 7 pm, we know that the temperature was 16°C. The problem states that at 2 pm, the temperature was 9°C warmer than this. So at 2 pm, the temperature is equal to 16°C+9°C = 25°C. To find the temperature at 8 am, we must subtract 10 from the temperature at 2 pm, since the problem states that 2 pm was 10°C hotter than 8 am. 25°C - 10°C = 15°C. Therefore, the temperature at 8 am is 15°C. You can work backward if necessary to check this information.

15°C + 10°C = 25°C - 9°C = 16°C

Hope this helps!
