Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: 13m
Concept: Vector Displacement.

Formula: \(\text{Total East Displacement} = d_1 + d_2\)

Solution:

  • North (12m) cancels South (12m).


  • Eastward movement = \(8\text{m} + 5\text{m} = 13\text{m}\).


Why other options are incorrect:

Option D: Sums all displacements without accounting for opposite directions.
