Final answer:

To find out how many minutes it took to cool the water to 100.3°F, you can use the given rate of change of temperature and the initial temperature of the water.

Step-by-step explanation:

To find out how many minutes it took to cool the water to 100.3°F, we need to use the given rate of change of temperature and the initial temperature of the water. Assuming the initial temperature of the water is higher than 100.3°F, and the temperature decreases at a rate of 2.5°F per minute, we can use the formula:

Time = (Initial Temperature - Final Temperature) / Rate of Change

Substituting the values, we have:

Time = (Initial Temperature - 100.3°F) / -2.5°F per minute

Let's calculate the time:

Time = (Initial Temperature - 100.3°F) / -2.5 = (Initial Temperature - 100.3) / -2.5
