Terry needs to run some errands. He walks 3 blocks east to get some cash from the bank. Then he walks 2 blocks further east to the pet store to pick up treats for his dog. Finally, he walks 4 blocks west to the baker's shop to pick up a birthday cake for his daughter. (East is the positive direction.) What is Terry's total displacement? (1 point)

Question

A. 9 blocks
B. 0 m
C. -1 blocks
D. 1 block

Answer 1

To determine Terry's total displacement, we need to consider the distances he traveled in both the east and west directions.

1. Terry first walks 3 blocks east: +3 blocks
2. Then he walks 2 blocks further east: +2 blocks
3. Finally, he walks 4 blocks west: -4 blocks

Now we can calculate his total displacement:

Total Displacement = (3 + 2 - 4) blocks Total Displacement = 5 - 4 Total Displacement = 1 block

Therefore, the correct answer is: D. 1 block.
