Direction sense · solved example
Ravi walks 5 km east, turns right and walks 5 km, then turns right again and walks 5 km. In which direction is he now from the starting point?
Solution
The east and west legs of 5 km each cancel, leaving him 5 km south of where he began, so he is due south.
Direction sense · solved example

Solution
The net movement is 5 km east and 12 km south, which places the person to the South-east of the start.
