A cyclist rides 60 meters north, then 80 meters south, and finally 70 meters north. What is the total distance the cyclist has traveled?
210 meters
Distance is the total length of the path actually covered, regardless of direction.
Add each leg: 60 m + 80 m + 70 m = 210 m.
(The net displacement would be smaller, but the question asks for total distance.)
Hence, the answer is 210 meters.
Which of the following statements correctly describes average velocity and its SI unit?
