4 miles south

4 miles north

Explanation:

Initially Scott travels 5 miles north at this point his displacement is 5 miles toward north

then he goes 3 miles south. which makes his displacement 2 miles (5 - 3 = 2) towards north as north and south are opposite directions.

finally he travels 2 miles due north.so his final displacement is

2 miles + 2 miles = 4 miles towards north direction
