Step 1

To determine the time t when the temperature of bottle inside the cooler is 20 degree Celsius.

Step 2

Given:

The temperature of the bottle in degree Celsius, t minutes after it is being place inside the cooler is given by the formula:

Step 3

Consider that the required temperature of the bottle is 20 degree Celsius.
