In July, the average temperature in one US city was 29°C. By December, the average temperature had fallen by 29°C. Explain why the average temperature in December was 0°C. 1-2 sentences
The average temperature in December was 0°C because the initial average temperature in July was offset by the decrease of 29°C.
The average temperature for July was 29°C. When it fell by 29°C in December, it reached 0°C, resulting in an average temperature of 0°C for that month.
To explain why the average temperature in December was 0°C, you would subtract 29°C from 29°C to get 0°C, since the temperature fell by the same amount as its initial value in July.
