Question

This graph shows the velocity of a runner moving along a straight path over time. According to the graph, which answer describes the runner's motion? A. The runner's velocity decreased over time. B. The runner's velocity was constant. C. The runner stopped moving. D. The runner's velocity increased over time.

Answer 1

The answer is infact B. There is no stopping or anything like that. He was constant the whole run.

Answer 2

Here, we can see acceleration is constant over time, but as time is increasing velocity is also increasing,.

Question is just for variation of velocity and as it is increasing over time your answer would be Option D

Hope this helps!
