Solution

To find the unit rate, you divide the total amount by the total time. In this case, you would divide 16°C by 4 hours.

Step 1: Identify the total amount and total time. The total amount is 16°C and the total time is 4 hours.

Step 2: Divide the total amount by the total time. 16°C ÷ 4 hours = 4°C/hour.

So, the unit rate of the temperature rise is 4°C per hour. Therefore, the answer is d4°C/h.
