Bhavesh starts from Point A and drives 19 km towards the east. He then takes a left turn, drives 16 km, turns left and drives 23 km. He then takes a left turn and drives 18 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.)
2 km to the north
Starting facing East and turning left at each step (East to North to West to South to East), the path covers 19 km East, 16 km North, 23 km West, then 18 km South, and finally 4 km East after a last left turn.
Plotting coordinates from the start (0,0): after all the moves, point P is reached at coordinates (0, -2).
Point A is at the origin (0,0), so from P the direction back to A is straight North, a distance of 2 km.
Hence, Bhavesh should drive 2 km to the north to reach Point A again.
