2) On a certain day, the temperature changed at a rate of \( -3^{\circ} \mathrm{F} \) per hour. How long did it take for the change in temperature to be \( -33^{\circ} \mathrm{F} \) ?

To find the time it took for the temperature to change by \( -33^{\circ} \mathrm{F} \) at a rate of \( -3^{\circ} \mathrm{F} \) per hour, you can use the formula: \[ \text{Time} = \frac{\text{Change in Temperature}}{\text{Rate of Change}} \] Plugging in the values: \[ \text{Time} = \frac{-33^{\circ} \mathrm{F}}{-3^{\circ} \mathrm{F/hour}} = 11 \text{ hours} \] So, it took 11 hours for the temperature to change by \( -33^{\circ} \mathrm{F} \). --- Temperature changes are not just numbers; they can create waves of excitement or chill! For example, a sudden drop in temperature can lead to a snow day—hurray for kids! Knowledge of temperature shifts is crucial for weather forecasting, helping people prepare for different conditions, whether it's simply bundling up or grabbing a swimsuit before heading to the beach. Feeling a bit chilly? Knowing how temperature change works can also help you in everyday life! For instance, if you find that your heater is running at full swing yet still not warming your space efficiently, it’s likely time for a maintenance check—lest you’ll be heating the entire neighborhood while freezing in your own living room!
