Jill walks 1 mile everyday for exercise, leaving her front porch at 9:00 A.M. and returning to her front porch at 9:25 A.M. What is the total displacement of Jill's walk?
To find the total displacement of Jill's walk, we need to determine the straight-line distance from her starting point to her ending point.
Jill walks 1 mile every day, so the distance she walks is 1 mile.
Since she returns to her front porch, her starting and ending points are the same. Therefore, the straight-line distance from her starting point to her ending point is zero.
Hence, the total displacement of Jill's walk is zero.
