1. **Stating the problem:** A birdwatcher sees an average of $p$ penguins each day. We want to find how many penguins they would expect to see in one hour. 2. **Understanding the problem:** There are 24 hours in a day. If the birdwatcher sees $p$ penguins in 24 hours, then the average number of penguins seen per hour is the total penguins divided by 24. 3. **Formula used:** $$\text{Penguins per hour} = \frac{\text{Penguins per day}}{\text{Hours per day}} = \frac{p}{24}$$ 4. **Explanation:** Since the total penguins $p$ are spread evenly over 24 hours, dividing by 24 gives the average per hour. 5. **Final answer:** $$\boxed{\frac{p}{24}}$$ This means the birdwatcher expects to see $\frac{p}{24}$ penguins in one hour on average.
