Answer:
2 miles east
Explanation:
A runner walks 1 miles to the west, turns around and jogs 4 miles to the east and finally turns again and sprints east 1 more mile. Therefore, the runner's displacement is 2 miles east. This question might be confusing to you because you have to make an assumption regarding which is the mistake in the question. It could either be the second turn or the second "East". We know that the runner's displacement is in the order: -1 + 4 − 1 = 2. Therefore, 2 miles east is the correct answer.
