Ben walks 500 meters from his house to the corner store. He then walks back toward his house but stops to talk to a neighbor when he is 200 meters from the corner store. If it takes Ben 910 seconds from the time he leaves his house until he stops to talk to his neighbor, what is his average velocity? (Round your answer to the nearest tenth of a meter per second.)
Ben’s average velocity is m/s.

Explanation:
Ben walks 500 meters from his house to the corner store. He then walks back toward his house but stops to talk to a neighbor when he is 200 meters from the corner store. If it takes Ben 910 seconds from the time he leaves his house until he stops to talk to his neighbor, what is his average velocity? (Round your answer to the nearest tenth of a meter per second.)
Ben’s average velocity is m/s.
Given - Distance walked 500 and 200 metres
Time - 910 seconds
Find - Average velocity
Solution - Distance walked by Ben is 500 metres and additional 200 metres. Now, as the question asks for velocity, displacement will be taken to solve for average velocity. Hence, total displacement is 500 - 200
Displacement = 300 metres
Now, calculating the average velocity by the formula displacement/time.
Average velocity = 300/910
Average velocity = 0.3
Average velocity of Ben is 0.3 metre/second.
