A person covers 12 km in 2 hours and returns the same distance in 3 hours. What is the average speed of the entire journey?

1. 4 km/h
2. 4.8 km/h
3. 5 km/h
4. 6 km/h

Correct answer: 4.8 km/h

Solution

The total distance is 12 + 12 = 24 km and the total time is 2 + 3 = 5 hours. Average speed = total distance / total time = 24/5 = 4.8 km/h.
