Explanation:

- Mira starts at point J, which is 4 feet east of point K. So, J is positioned relative to K at a 4 feet distance on the east-west axis.

- Point P is to the west of Q by 4 feet and is aligned vertically north 10 feet from J. Thus, P is directly above J.

- Point Q is positioned directly to the east of P by 4 feet, making J and Q aligned in the same vertical line, with Q further east relative to J.

- Point S is south of Q by 10 feet.

- Point R is the midpoint on the vertical line between Q and S.

- Point U is north of point V by 5 feet, and R is west of U by 4 feet, placing U directly above R on the north-south axis.

- The distance between K and J is 4 feet east.

- The distance from J to S, directly below Q, is 10 feet down.

- Total distance from K to S is therefore calculated as 4 feet east to reach J, then 10 feet down to reach S, totaling a straight line path of 8 feet from K in a diagonal direction.

Thus, the correct option is:

- Option 4: 8 feet
