Certificates / Logical reasoning / Directions and Distances

Directions and Distances: lesson, then the certificate test

Step 1: the lesson (about 1 min)

Draw every move on a small sketch with North at the top.

  • A right turn while facing North means East; while facing South it means West.
  • The shortest distance back to the start uses Pythagoras: √(x² + y²).
  • Name the final direction from the START point to the end point unless asked otherwise.

Worked example

Walk 6 km North, turn right and walk 8 km. How far are you from the start, and in which direction?

  • Facing North, a right turn faces East
  • Distance = √(6² + 8²) = √100 = 10 km
  • You are North and East of the start

Answer: 10 km, North-East

Watch out

  • Left and right depend on the way the person is facing at that moment.
