A person walks 5 km to a destination in 1 hour. On the return journey, they walk the same 5 km distance back to the starting point in 30 minutes. What is the average speed of the person for the entire journey?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 6.67 km/h.
Total distance = 5 + 5 = 10 km
Total time = 1 hr + 0.5 hr = 1.5 hrs
Average speed = 10 ÷ 1.5 = 6.67 km/h
