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?
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.
