Question

5. The temperature at 12 noon was 10°C above zero. If it decreases at the rate of 2°C
per hour until midnight, at what time would the temperature be 8°C below zero!
What would be the temperature at mid-night?​

Answer 1

Answer:

Step-by-step explanation:

At 12 pm it was 10C

By the rate of 2C per hour

At 1 pm it should be 8C above zero

Therefore if every hours counts for 2C

Then -8C should be reached when 18C is decreased

18C = 9 hours

12 pm + 9 hours = 9pm

I guess i am correct
