Question

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?

0.2 m/s
0.5 m/s
0.7 m/s
1.2 m/s

Answer 1

`velocity = 0.2 m/s`

Step-by-step explanation:

As we know that Ben walks to the market at distance of 500 m

then he turns back towards his house and continue 200 m past his house towards neighbor.

So the return path length is 700 m

So here total displacement of Ben is given as

`d = 700 - 500`

`d = 200 m`

Now for the average velocity we know that

`velocity = (displacement)/(time)`

`velocity = (200)/(17 * 60 seconds)`

`velocity = 0.2 m/s`
