Respuesta :

Answer:

Average velocity of Ben = 5.1 m/s

Explanation:

 Average velocity = Total displacement / Time taken for that displacement.

 Ben walks 500 meter from his house to the corner store. He then walks back towards his house , but continues 200 meters past his house to talk to a neighbor

 So his total displacement =  200 meters

 Time taken for this = 17 minutes = 17 * 60 = 1020 seconds.

  Average velocity = 1020/200 = 5.1 m/s

So average velocity of Ben = 5.1 m/s
