Using the relation between position and velocity, it is found that:
- A: Her speed increased at a consistent rate.
- B: She stopped at an intersection.
- C: Her speed increased at a consistent rate.
<h3>Relation:</h3>
- The velocity is the derivative of the position, that is, it is the rate of change of the position.
For each part, we have that:
- In part A, her <u>distance is increasing</u>, which means that the velocity is also increasing. The graph is a line, hence the derivative is a constant, which means that the increase was constant.
- In part B, she remains at the <u>same position</u>, hence, she stopped at an intersection.
- Part C is <u>similar to part A</u>, distance increasing, hence velocity increasing at a constant rate.

Answer:
A)
Step-by-step explanation:
Answer:
6% of the racers did not ocmplete the marathon
Step-by-step explanation:
290 racers
272 completed the race
15 + 3 = 18 did not complete the race
= 0.94 = 94%
= 0.06 = 6%
