![**PHASE 2:**
A path goes around a triangular park, as illustrated in the diagram.
**Diagram Explanation:**
- The diagram is a grid with the x-axis labeled "Distance (yd)" and the y-axis labeled "Distance (yd)" as well.
- Key points in the triangle are labeled P, Q, and R, forming a right triangle shape.
- Coordinates for these points need to be examined relative to the grid.
**Tasks:**
1) Determine the coordinates of point S on the directed line segment \( PR \) that divides the segment in the ratio 2 to 1.
2) Calculate the distance around the park to the nearest yard.
3) A new path and a bridge are constructed from point Q to the midpoint M of \( PR \). Calculate QM to the nearest yard.
4) A man jogs from P to Q to M to R to Q and back to P at an average speed of 150 yards per minute. Approximately how many minutes does it take? Explain your reasoning.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0f9ffbbc-0b94-43e2-96f7-d1a78eefb4aa%2Fd9959f0c-3d12-475e-bf48-f6b4b3644720%2Fyha306h_processed.jpeg&w=3840&q=75)
