A cyclist travels 2 km north in 10 minutes, then turns and travels 1 km south in 5 minutes. What is the cyclist's average speed for the entire journey?

Options

• 0.2 km/min

• 0.067 km/min

• 0.1 km/min

• 3 km/min

0.2 km/min

Explanation:

This result is obtained by correctly calculating the total path length (2 km + 1 km = 3 km) and dividing by the total time (10 min + 5 min = 15 min).
