Final answer:
Julio's total distance traveled is 2 miles, and because he ends back at the starting point after running around the loop, his displacement is 0 miles. The correct answer to the student's question is (A) 2 miles and 0 miles.
Step-by-step explanation:
The question regarding Julio's run around the track involves understanding the concepts of distance and displacement in physics. Distance is the total length of the path traveled by an object, regardless of its direction, while displacement is the straight line distance between an object's starting point and ending point, along with the direction of the straight line. If Julio's track is a quarter of a mile long, and he runs around it eight times, the total distance he travels is 8 times a quarter of a mile, which is 2 miles (8 x 0.25 = 2). Since the track is a loop, the displacement is 0 miles because he ends up at the starting point.
