Question

Damian is watching the temperature of the swimming pool. It is currently 86.6° and cooling 0.5° per minute. After how many minutes will the swimming pool be 80.8°? ​

Answer 1

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.
