Mr. Vasu starts from Point A and drives 25 km towards the north. He then takes a left turn, drives 17 km, turns left and drives 9 km. He then takes a right turn, drives 5 km, turns left and drives 20 km. He then takes a left turn and drives 29 km. He takes a final left turn, drives 4 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.)
7 km to the west
Starting facing North and turning left each time (North to West to South), the path covers 25 km North, 17 km West, 9 km South, reaching (-17, 16) before the direction changes.
A right turn (West to North is wrong; from South, a right turn heads West) and 5 km West brings the path to (-22, 16). A left turn (West to South) and 20 km South brings it to (-22, -4).
A left turn (South to East) and 29 km East brings the path to (7, -4). A final left turn (East to North) and 4 km North brings point P to (7, 0).
Since A is at the origin (0, 0) and P shares the same y-coordinate, only a horizontal move is needed: 7 km West from P reaches A.
Hence, Mr. Vasu should drive 7 km to the west to reach Point A again.
