| 1. Let’s denote the length of the segment BC by x.
2. Determine the length of the segment AC:
4 * x = 4x cm.
3. Let’s compose and solve the equation:
4x + x = 15;
5x = 15;
x = 15: 5;
x = 3.
4. The length of the BC segment is x = 3 cm.
5. What is the length of the speaker section?
4 * x = 4 * 3 = 12 cm.
Answer: the length of the AC segment is 12 cm.
