when or in which condition 'distance and displacement' is the same?

When an object moves in a straight line without coming back, it's displacement and distance magnitude will always be equal.
1)why not travelling backwards?
Displacement is is a vector quantity and distance is a scalar quality.
So if you walk on a line ABC, and you walk from A to C and then walk backwards to B:
Your total displacement will be, AC - CB this is because displacement is a vector and it considers direction.
You total distance travelled will be, AC + CB this is because distance is a scalar and it doesn't consider direction.
Now it's clear that why the obeject shouldn't come back for them to be equal.
