Direction sense — tourist's net direction from start A tourist drives 10 km West, turns left 4 km (South), then East 4 km, turns right 5 km (South), then left 6 km (East). In which direction is he from the starting point?

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

Given Data / Assumptions:x: −10 + 0 + 4 + 0 + 6 = 0; y: 0 − 4 + 0 − 5 + 0 = −9.

Concept / Approach:Zero x but negative y ⇒ due South of start.

Final Answer:South
