Show answer and solution
Answer: (b)
- Final (home) position of A is lower on the axis than that of B, so A lives closer: (A) true, (B) false.
- A starts at while B starts later and moves faster, so A takes more time: (C) false.
- B's line is steeper, so B has the larger velocity: (E) true, (D) false.
- So the answer is (b) (A) and (E) only.
