Show answer & explanation

Correct answer: D

Answer: 5 km towards South

Reasoning:

  1. Place Town A at coordinates (0, 0). Town D is 13 km east of A, so Town D is at (13, 0).

  2. The bus travels 8 km west from A to reach (-8, 0).

  3. It then takes a right turn (from west → right = north) and goes 5 km to reach B at (-8, 5).

  4. From B it takes another right turn (from north → right = east) and travels 21 km to reach the final point at (-8 + 21, 5) = (13, 5).

  5. Compare the final point (13, 5) with Town D (13, 0): they share the same east‑west coordinate, and the final point is 5 km north of Town D.

  6. Therefore, to reach Town D from the bus's final position you must travel 5 km towards South.
