A person starts at point A and walks 5 blocks North, then 3 blocks West, then 2 blocks South and finally 1 block East. What is the person's final position relative to point A?
- A2 blocks West and 3 blocks North
- B4 blocks West and 4 blocks North
- C1 block West and 2 blocks North
- D7 blocks West and 3 blocks North
Solution & Step-by-step Explanation
Let's track the movement on a Cartesian coordinate plane assuming point A is at the origin :
1. Walks 5 blocks North:
2. Walks 3 blocks West:
3. Walks 2 blocks South:
4. Walks 1 block East:
Relative to the starting point , the coordinates mean the person is exactly 2 blocks West and 3 blocks North.
