An ostrich runs north in a straight line for 21 meters. She then turns around and runs 25 meters back toward her nest (south) on the same path. What is her displacement?

What is i.p.c. supposed to mean?
21  25 = 4.
I used positive numbers for north displacement , so the minus sign means it ends up 4 meters south
