Ben walks 500 meters from his house to the corner store. He then walks back toward his house, but continues 200 meters past his house to talk to a neighbor. It takes Ben 17 minutes from the time he leaves his house until he stops to talk to his neighbor.What is Ben’s average velocity? Round to the nearest tenth.

Ben’s displacement is 200 meters from his house, because he ends 200 meters past where he started. The total time is 17 minutes, or 17 × 60 = 1,020 seconds. Average velocity is displacement divided by time: 200 ÷ 1,020 ≈ 0.196 m/s, which rounds to 0.2 m/s. The correct choice is A, 0.2 m/s.
