Answer:
12 minutes
Step-by-step explanation:
First we need to look at the change in the two temperatures:
86.6-80.8= 5.8
Next we know that every minute the temperature drops half of a degree so we will find how many minutes until it reaches 80.8:
5.8/0.5= 11.6
Round the answer up to 12 minutes to have a whole number and the pool will be at 80.8 degrees or lower in 12 minutes.
