1. **State the problem:** We want to find the snowfall rate per hour given that 3 inches of snow fell from 1:00 pm to 12:00 am the next day. 2. **Identify the time interval:** From 1:00 pm to 12:00 am is 11 hours. 3. **Formula for rate:** Rate = \frac{\text{Total snowfall}}{\text{Time in hours}} 4. **Apply the values:** $$\text{Rate} = \frac{3 \text{ inches}}{11 \text{ hours}}$$ 5. **Simplify the fraction:** $$\text{Rate} = \frac{\cancel{3} \times 1}{\cancel{11} \times 11} = \frac{3}{11} \approx 0.2727 \text{ inches per hour}$$ 6. **Interpretation:** The snowfall rate is approximately 0.27 inches per hour, meaning on average, about a quarter inch of snow fell each hour during that period.
