Question

Paritosh starts from Point A and drives 22 km towards South. He then takes a right turn, drives 12 km, turns right and drives 26 km. He then takes a right turn and drives 23 km. He takes a final right 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.)

The correct answer is
11 km to the west

Calculating Paritosh's Final Position

We can track Paritosh's movement using coordinates, assuming Point A is at the origin (0, 0).

  • Starts at A: (0, 0)
  • Drives 22 km South: Position becomes (0, -22)
  • Turns right (now facing West), drives 12 km: Position becomes (-12, -22)
  • Turns right (now facing North), drives 26 km: Position becomes (-12, -22 + 26) = (-12, 4)
  • Turns right (now facing East), drives 23 km: Position becomes (-12 + 23, 4) = (11, 4)
  • Turns right (now facing South), drives 4 km: Position becomes (11, 4 - 4) = (11, 0)

Paritosh stops at Point P, which is located at coordinates (11, 0).

Finding Distance and Direction to Point A

Point A is at (0, 0) and Point P is at (11, 0).

  • The difference in the x-coordinates is \(11 - 0 = 11\).
  • The difference in the y-coordinates is \(0 - 0 = 0\).

The shortest distance between P and A is the difference along the x-axis, which is 11 km.

Since Point P (11, 0) is to the east of Point A (0, 0) on the coordinate plane, Paritosh must drive West to return to Point A.

Therefore, Paritosh needs to drive 11 km to the west to reach Point A again.
