Show answer & explanation
Correct answer: B
Solution:
Start at the origin and walk 25 m south.
Turn left (when facing south, left is east) and walk 20 m east.
Turn left again (from east, left is north) and walk 25 m north.
Turn right (from north, right is east) and walk 15 m east.
Net vertical displacement: 25 m south + 25 m north = 0 (they cancel).
Net horizontal displacement: 20 m east + 15 m east = 35 m east.
Final answer: 35 meters East
