It also moves 19 km east so it will have a horizontal length of 19.
Since north and south have different vectors, or different slope they will form perpendicular lines so it forms a right angle.
Since it has a right angle and it ask for displacement (which is the distance between the two directions) we use the pythagorean theorem.

where r is displacement and a and b are the vectors.




which is about 22.5
