# A car travels \( 60 \) \( \text{km} \) at \( 30 \) \( \text{km/h} \), then \( 60 \) \( \text{km} \) at \( 60 \) \( \text{km/h} \). What is its average speed over the entire trip?

A car travels \( 60 \) \( \text{km} \) at \( 30 \) \( \text{km/h} \), then \( 60 \) \( \text{km} \) at \( 60 \) \( \text{km/h} \). What is its average speed over the entire trip?

- **A.** \( 45 ~ \text{km/h} \)
- **B.** \(40 ~ \text{km/h} \)
- **C.** \( 42 ~\text{km/h} \)
- **D.** \( 48 ~ \text{km/h} \)
