Final answer:
After examining Sarita's movement pattern and canceling out the opposite directions, it is concluded that Sarita must move in the northeast direction to return to her home. The final direction Sarita is moving towards is therefore northeast, which is the opposite direction of southwest. Answer: c) North east
Step-by-step explanation:
The student's question involves determining the final direction Sarita is facing when she returns home after walking in different directions. If Sarita walks 25m in the northwest direction, then 25m in the southwest direction, and finally 25m in the southeast direction, we can analyze her movements on a Cartesian plane. The northwest and southeast movements cancel each other out since they are opposite directions. The result is that she needs to move northeast to return home because this direction is opposite to the southwest direction she last traveled.
The final direction Sarita is moving towards is therefore northeast, which is the opposite direction of southwest. Answer: c) North east
