Holden is trying to determine the velocity of his race car. He went 20 meters east, turned around, and went 40 meters west. His car was 20 meters from the starting line. This took 5 seconds.

What is the car’s average velocity?

4 m/s east
4 m/s west
12 m/s west
12 m/s east

Answer 1

answe is four m west

Answer 2

4 m/s west

Explanation:

Because he went only 20 meters east and then went 40 meters west, he would be going west. Then when you divide the displacement, which you get by subtracting the 2 numbers, by 5 seconds, you get 4 m/s. I'm sorry if I'm wrong.
