■ Concept:
●Distance is defind as total lengh of path which is covered by body.
●Displacement is defind as the shortest distance between two points.
⏭■Calculation:
Total Distance
●Distance = 3 + 4 + 9
● Distance = 16 km
■Total displacement
s=root (12^2+4^2)
s=root (144+16)
s=root160
● Displacement ≈ 12.64 km
hope it helps u dear.......
