To find out how many minutes the liquid can stay in the cooler, we need to determine how many minutes it takes for the liquid's temperature to drop below 60.5°F from its initial temperature of 88.6°F.
The rate at which the temperature decreases is 2°F per minute.
To find the number of minutes it takes for the liquid's temperature to drop by 28.1°F (88.6°F - 60.5°F), we divide the temperature decrease by the rate of decrease:
28.1°F / 2°F = 14.05 minutes.
Therefore, the liquid can stay in the cooler for approximately 14.05 minutes before its temperature drops below 60.5°F.
For an experiment, the temperature of a liquid must stay above 60.5°F. The starting temperature of the liquid is 88.6°F. It is placed in a cooler, which lowers its temperature 2°F each minute.
How many minutes can the liquid can stay in the cooler?
