Answer 1

Answer:

Step-by-step explanation:

The temperature at 12 noon was 30 °C above zero. If it decreases at the rate of 3 °C per hour until midnight, at what time would the temperature be 18 °C. What would be the temperature at night 2 a.m.?​

Answer:

At 12 noon it was 30°C,

decreasing rate of temperature is 3°C per hour,

So at 1 am it will be 30 -3 ,

27° C,

Continue,calculating like that:

2 am=27-3=24°C,

So at 2 am the temperature will be 24°C.

3 am=24-3-21°C,

4 am=21-3=18°C,

So at 4 am the temperature will be 18°C.

Hope it helps you.
