1)
the distances are :
AB = 20 km            CD = 4 km            CB = 8 km

finding:
DB = CB - CD =  8 - 4 = 4 km
AC = AB - CD = 20 - 8 = 12 km

Displacement associated with direction also along with a magnitude.  Let us say that the displacements towards the right side direction are positive.  The displacements towards the left are negative.  Let the unit vector towards right be denoted by .

Displacements:

=====================
2)  distances :  AB = 15 km      AD = AB - DC - CB = 15 - 5- 8 = 2 km
DC = 5 km             EB = DB - DE = 5 + 8 - 11 = 2 km
CE = CB - EB = 8 - 2 = 6 km

displacements :

you can write the other displacements from some more  points to others, in the same manner.
