**Question 21:**

If a car travels 792 feet in 12 seconds, what is the speed of the car in miles per hour?

- **Explanation:**
  - To convert the speed from feet per second to miles per hour, first calculate feet per second by dividing the distance by time: \( \frac{792 \, \text{feet}}{12 \, \text{seconds}} \).
  - Convert feet per second to miles per hour:
    - 1 mile = 5280 feet
    - 1 hour = 3600 seconds
  - Use the conversion: \(\frac{\text{feet/second} \times 3600 \, \text{seconds/hour}}{5280 \, \text{feet/mile}} \).

This formula gives the speed in miles per hour.
