Sam and Sally are both running the mile at the region track meet. One mile equals four laps around the oval track. They are neck and neck during most of the race, but at the half-mile mark Sam starts to pull ahead. He wins the race with a time of 5 minutes 25 seconds. Sally stops at .9 miles to have a drink of water and then continues to the finish line.
How does Sam and Sally's displacement compare for the race?
A) Their displacement is the same, zero miles.
B) Sam's displacement is greater than Sally's.
C) Sally's displacement is greater than Sam's.
D) Both Sam and Sally's displacement is 1 mile.

The whole passage is just distraction I guess !!

Both finishes the finish line thus the diaplacement for both is Zero !!

So in my opinion the most appropriate answer is A !!

Answer:

The correct answer is option A, Their displacement is the same, zero miles

Explanation:

In a track meet , race is around a circular path and all the athletes are required to reach the point from where they have started. If both Sam and Sally started from point A and B in two different track and finished the race at the same points A and B then the total displacement will be zero as there is no change in their final and initial position. Rest all information given in question is just to divert the mind of reader.
