Explanation:
[tex]\text{Velocity is defined as the average displacement per unit time.}[/tex]
[tex]\text{Since the car is moving at a steady velocity, the velocity does not change over time, it shows a horizontal line on the }v-t\text{ graph}[/tex]
[tex]\text{Therefore, only option 2,5,8 matches this requirement.}[/tex]
[tex]\text{Since the car is moving to the right, which is defined as the positive direction in this question, the velocity (}v\text{) is also positive.}[/tex]
[tex]\text{Therefore, only option 5 is correct.}[/tex]
