Question

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

Step-by-step explanation:

The temperature at 12 noon was 10 C

Per hour it decrease 2 C

The temperature be 8 C below zero at nine p. m. because first this 8 C os like this -8

So there was a temperature would be to decrease -18 C so divide 18/2 there will be come 9 so after nine hour from noon there was a temperature -8

and at midnight there was a 12 hour left so multiply 12×2 there was a come 24 so +10-24=-14 so Temperature at midnight will be -14 C
