PLS MARK ME AS BRAINLIEST ANSWER THANK YOU !!!

Step-by-step explanation:

1 hour = - 3°C

12 noon until 12 midnight = 12 hours

12 hours = 3°C × 12 = -36°C

15 °C - 36° C = -21 °C

temperature at midnight = -21 ° C

15°C - 18 °C = - 3° C

18°C ÷ 3°C = 6 hours

12 noon + 6 hours = 6 evening

temperature at - 3°C = 6 pm / 6 evening
