The position in the graph between 4 - 6 seconds is the region of constant velocity.
<h3>What is constant velocity?</h3>
The term constant velocity refers to the period in the graph when the velocity is not changing with time. As such, the graph is shown to be a flat portion at such a point.
Hence, it follows that the position in the graph between 4 - 6 seconds is the region of constant velocity.
