Problem solving | should your directions to a friend for traveling from one city to another include displacements or distances? explain.

This should include distances.  Displacement is the shortest distance from point A to point B.  Distance is the total length of travel.  For an example I have included a simple map.

Displacement would not be an accurate representation of the driving instructions because it would not tell the total length of travel.  Basically, the driver would be going through buildings if you told them displacement.  Directions would tell them the roads traveled.
