Answer:

  • Considering the temperature is 0°C and
  • It is changing at a rate of -3 per hour.

So, it took 11 hours for the change in temperature to be -33.

Step-by-step explanation:

Rate of change basically means the amount of change to how long it takes for the change to occur.

Rate of change = Change in Value/ Change in time

On a certain day the temperature changed at a rate of -3 per hour.

Let suppose the Temperature at 8:00 = 0°C

As the temperature changed at a rate of -3 per hour.

It means the Temperature at 9:00 = -3°C.

so

Rate of change = (-3 - 0)/(9:00 - 8:00) = -3°C per hour

So, the temperature to be -33°C, it would take 11 hour as -3 × 11 = -33.

Therefore, it took 11 hours for the change in temperature to be -33.
