To calculate the unit rate in parts per hour, we can divide the total number of car parts by the total number of hours.

Given:
- Total car parts = 4,800
- Total time = 8 hours

The unit rate is:

\[
\text{Parts per hour} = \frac{4800}{8} = 600
\]

So, the correct answer is **600 parts per hour**.

Here are 5 related questions:
1. How would the unit rate change if only 4 hours were worked instead of 8?
2. How do you calculate the unit rate if the number of hours is a fraction (e.g., 7.5 hours)?
3. What if the number of car parts was doubled—what would the new unit rate be?
4. How do unit rates apply to other real-life examples like speed or productivity?
5. If 500 parts were faulty, how would that affect the unit rate of *working* parts per hour?

**Tip**: Always break down total amounts by time to find rates or speeds!
