A car travels $6.0 k m$ along a main road in $6.0$ minutes. It then travels $2.0 k m$ along a minor road in $6.0$ minutes. Which calculation of average speed for the whole journey is correct?

Total distance traveled is $8 + 2 k m$
Total time taken is $6 + 6 m i n$
Average speed is $= \frac{8}{12} = \frac{2}{3} = 0.67 k m / m i n$
