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?

0.196 m/s

Explanation:

Average displacement is defined as the total displacement covered to the total time taken.

Total displacement = 500 - 500 - 200 =  - 200 m

Total time taken = 17 minutes = 17 x 60 = 1020 second

So, Average velocity = 200 / 1020 = 0.196 m/s (magnitude only)
