an ant walks 4 cm East, gets some rest, and continues for another 3 cm in the same direction.
What is the total displacement traveled by the ant?

"Total displacement" is how far the ant has travelled from the starting point. Note that, in this case, it keeps going in the same direction.
Surely you can figure this out by yourself.
