While walking on a plane surface, a traveler first headed 19 miles north, then 16 miles west, then 3 miles south and finally 4 miles east. How many miles from the starting point was the traveler after these four legs of the journey?
+633 I assumed, based off of the wording, that this was based on displacement. The question is, "How many miles from the starting point was the traveler after completing these 4 legs of the journey"
+633 I'm assuming this is absolute distance, not distance traveled on foot.
19 - 3 = 16
16 - 4 = 12
√162+122=√256+144=√400=20
He moved an overall of 20 miles from the starting point.
