3. Calvin's house is 30 miles due west of Meave's house, and Selena's house is 40 miles due south of Meave's house.
- A. The quantity in Column A is greater.
- B. The quantity in Column B is greater.
- C. The two quantities are equal.
- D. The relationship cannot be determined from the information given.
Correct Answer: B
Explanation:
The answer is B
