Transcribed Image Text:**Problem Description:**
Two people start at the same place and walk around a circular lake in opposite directions. One has an angular speed of \(1.93 \times 10^{-3}\) rad/s, while the other has an angular speed of \(5.81 \times 10^{-3}\) rad/s. How long will it be before they meet?
**Diagram Explanation:**
- **Circular Lake:** The diagram depicts a top-down view of a circular lake with a path around it.
- **Path:** The circular path is shown with yellow dashed lines, indicating the direction of movement.
- **Start and End Points:** The points labeled "Start" and "End" represent the initial and meeting points.
- **Angles:** Two angles, \(\theta_1\) and \(\theta_2\), are marked, showing the angular displacement of each person as they walk around the lake.
**Answer Entry:**
- **Number Box:** A box is provided to enter the numerical answer to the problem.
- **Units Dropdown:** A dropdown menu is provided to select the appropriate units for the answer.
