# You drive \( 4 \) \( \text{km} \) at \( 30 \) \( \text{km/h} \) and then another \( 4 \) \( \text{km} \) at \( 50 \) \( \text{km/h} \). What is your average speed for the whole \( 8 \) \( \text{km} \) trip?

You drive \( 4 \) \( \text{km} \) at \( 30 \) \( \text{km/h} \) and then another \( 4 \) \( \text{km} \) at \( 50 \) \( \text{km/h} \). What is your average speed for the whole \( 8 \) \( \text{km} \) trip?

- **A.** More than \( 40 \) \( \text{km/h} \)
- **B.** Equal to \( 40 \) \( \text{km/h} \)
- **C.** Less than \( 40 \) \( \text{km/h} \)
- **D.** Not enough information
