Answer 1

The distance of the present location of the person from the starting point is-

5 km.

The track the person is following makes a parallelogram.

• First the person moves 3 km towards his right side.
• then moves 5 km slanting towards the south, i.e north east side
• then the person moves 8 km towards the left side.
• then finally travels 5 km slanting towards north, i.e north east.

All these directions makes a parallelogram having a gap of 5 km between the starting and ending point.
