(All turns are 90° turns only unless specified.)
  1. A3 km to the north
  2. B4 km to the north
  3. C5 km to the north
  4. D6 km to the north
Show answerHide answer

Correct answer: (A) 3 km to the north

Explanation

Official answer key: (1) 3 km to the north Correct answer should be (3) 5 km to the north. Taking A as the origin: 23 km west → (−23, 0); right turn (north) 27 km → (−23, 27); right (east) 29 km → (6, 27); right (south) 32 km → (6, −5); right (west) 6 km → P (0, −5). P is 5 km due south of A, so he must drive 5 km to the north. Scoring follows the official key.
