Driving with two left turns on an L-shaped route: A man drives 6 km West, turns left and drives 3 km (South), then turns left and drives 3 km (East). What is his final direction from the start?

Difficulty: Easy

Correct Answer: South-West

Explanation:


Introduction / Context:
Compute net displacement components to infer the bearing from the origin.


Given Data / Assumptions:

  • West 6 ⇒ x = −6.
  • Left from West is South 3 ⇒ y = −3.
  • Left from South is East 3 ⇒ x increases by 3 (to −3).


Concept / Approach:
Net vector from origin = (−3, −3) which lies diagonally to the South-West.


Step-by-Step Solution:

Start (0,0) → (−6,0) → (−6,−3) → (−3,−3).Direction from start to end: SW.


Verification / Alternative check:
Equal magnitude in West and South components implies a 45° SW direction.


Why Other Options Are Wrong:
They put the endpoint in different quadrants.


Common Pitfalls:
Answering the facing after the last turn (East) instead of the direction from start (SW).


Final Answer:
South-West
