Answer: 60m

Explanation:

Displacement is defined as the distance covered by a body or object in a specified direction.

If the dog runs 80m northwards i.e +80m since it runs along the positive y direction.

Also the dog returns to its master 20m in the south direction i.e -20m in the negative y direction.

Its total displacement will be +80-20 = 60m
