L is 13 km South of K; M is 10 km East of L; N is 5 km North of M. In which direction is N from K?

Important Notes

• Draw a north arrow before solving and take East as positive x, West as negative x, North as positive y, and South as negative y. |
• Apply every turn from the person's current facing direction. A right turn changes direction clockwise; a left turn changes it anticlockwise. |
• Combine opposite movements before calculating distance: cancel East with West and North with South. |
• Decide the final direction from the signs of the remaining horizontal and vertical displacements. For example, positive x and negative y indicate South-East. |
