Answer: D

8.403 m/s

Explanation:

Given that the women's world record for the 400-meter run around an oval track is held by Marita Koch, with a time of 47.60

seconds.

Her average velocity during this race will be

Velocity = distance/ time

Velocity = 400 / 47.6

Velocity = 8.403 m/s

Therefore, her average velocity during this race will be 8.403 m/s

D is therefore the correct answer.
