Direction sense — moped rider's last heading A rider starts at a point, goes 4 km South, then turns left and rides 2 km (East), then turns right and rides 4 km. Towards which direction is he moving now?

Introduction / Context:
This problem asks for the traveller's current heading (facing) after a short sequence of orthogonal moves and turns.

Given Data / Assumptions:

• Start heading: South.
• Path: South 4 km → left (to East) 2 km → right (to South) 4 km.
• All turns are 90°.

Concept / Approach:
Track heading after each turn; distances do not affect the final facing—only the turn sequence does.

Step-by-Step Solution:
Start facing South.Left from South ⇒ face East.Right from East ⇒ face South.Final leg is toward South; therefore the current heading is South.

Verification / Alternative check:
Sketching a quick compass-box diagram (S→E→S) confirms the orientation.

Why Other Options Are Wrong:
North/East/West correspond to other headings not obtained after the final right turn.

Common Pitfalls:
Confusing final position with facing. The question asks “towards which direction is he moving now?”—that is, heading.

Final Answer:
South
