15 meters north. the object is only moving away from the original starting place. its not like its moving away and then back again.

"Displacement" in physics usually referrs to the net change in position - meaning, take a snapshot of the dog before he starts moving and a snapshot of the dog when he's finished moving, and the distance between his two positions is his net displacement. Nothing he does in between affects the result - only where he starts and where he ends up.If you walk 6 meters north and then turn around and walk 4 meters south, I hope it makes sense that you are now standing 2 meters north of the point where you started. This is your net displacement (2 meters north).
15 meters north. the object is only moving away from the original starting place. its not like its moving away and then back again.
30 meters south
the east /west distances are the same but the north south are different. so subtract the north from the south distances and you end up with 60 meters south.
Vector quantities are quantities that have directionality as well as magnitude. Displacement (meters North) vs Distance (meters) Velocity (meters per second North) vs Speed (meters per second)
The answer is 80 because 100-30+10 is 80.
20m
The craft's velocity is 232 meters per second north.
