Yaman starts from Point A and drives 18 km towards the west. He then takes a right turn, drives 19 km, turns right and drives 21 km. He then takes a right turn and drives 23 km. He takes a final right turn, drives 3 km and stops at Point P. How far (shortest distance) and towards which direction should he drive in order to reach Point A again? (All turns are 90-degree turns only unless specified.)
4 km to the north
Starting facing West and turning right at each step (West to North to East to South to West), the path covers 18 km West, 19 km North, 21 km East, and 23 km South, reaching coordinates (3, -4) from the start.
The final right turn (from South to West) followed by 3 km West brings point P to coordinates (0, -4).
Point A is at the origin (0, 0). Since P and A share the same x-coordinate, only a vertical move is needed: 4 km North from P reaches A.
Hence, Yaman should drive 4 km to the north to reach Point A again.
