The problem on the screen describes a physical activity designed to train agility and explosive power in students. Here's a summary of the problem:

1. Scenario: A teacher (Pak Subur) designs an exercise where students must run from a starting point, touch a wall, and then run back to touch a flag (bendera). The diagram shows:

   • Distance from the start to the wall is 9 meters.
   • The distance from the start to the flag (on the ground) is 8 meters.
   • The height of the wall is 6 meters.

2. Optimal Path: The second part of the problem mentions that after several attempts, one of the students (Eko) discovers that the shortest path involves a reflection principle. This means that the student should treat the wall as a mirror, and the shortest route would be a straight line as if the flag's position is reflected on the other side of the wall.

The problem is likely asking you to determine the shortest path based on this reflective property, using geometric methods, such as the Pythagorean theorem.

Would you like a detailed step-by-step solution for calculating the shortest path, or any specific explanation?
