The problem you have provided involves three runners (Wibowo, Yudhi, and Zohri) who are training on a circular track, with the positions and dimensions provided in the first image. The second image presents a question about Zohri's running speed.

### Key details:
1. **Track dimensions**: 
   - The inner radius of the circular track is 28 meters.
   - The outer radius of the track is 56 meters.
2. **Distance between each runner**: 1.75 meters.
3. **Zohri's running speed**: 20 km/h.
4. **Laps completed by Zohri**: 30 laps.

### Problem in the second image:
The question asks for the time Zohri will take to run 30 laps of the track at a speed of 20 km/h.

### Solution:

1. **Track circumference**:
   The given radii correspond to the inner and outer lanes. Since Zohri's specific lane isn't mentioned, I'll calculate using the average radius:
   
   \[
   \text{Average radius} = \frac{28 + 56}{2} = 42 \, \text{meters}
   \]

   The circumference of a circle is given by:

   \[
   C = 2\pi r
   \]

   Substituting the average radius:

   \[
   C = 2\pi \times 42 \approx 263.89 \, \text{meters}
   \]

2. **Total distance**:
   Zohri runs 30 laps, so the total distance is:

   \[
   \text{Total distance} = 30 \times 263.89 \, \text{meters} = 7916.82 \, \text{meters} = 7.91682 \, \text{km}
   \]

3. **Time taken**:
   Zohri runs at a speed of 20 km/h. The formula for time is:

   \[
   \text{Time} = \frac{\text{Distance}}{\text{Speed}} = \frac{7.91682 \, \text{km}}{20 \, \text{km/h}} = 0.3958 \, \text{hours}
   \]

   Converting hours to minutes:

   \[
   0.3958 \, \text{hours} \times 60 = 23.75 \, \text{minutes}
   \]

### Answer:
The closest option to this calculation is not directly available. However, rounding suggests **20 minutes** (option E) is the closest reasonable answer based on typical assumptions in such problems.

Would you like further clarification or additional details? Here are five related questions to deepen understanding:

1. How would the time change if Zohri ran on a different lane of the track?
2. What would the effect be on the time if the running speed was increased to 25 km/h?
3. How does the average radius formula apply to this kind of track problem?
4. If Wibowo, Yudhi, and Zohri maintain different speeds, how can we calculate the time each would take to complete 30 laps?
5. What is the relationship between lap distance and the radius in circular tracks?

**Tip**: When solving running-related problems, always clarify the exact lane or path of the runner to get more accurate results.

Apabila Zohri berlari dengan kecepatan 20 km/jam pada lintasannya sebanyak 30 putaran, maka waktu yang ditempuh Zohri sekitar ... menit

Learn how to calculate the time taken by Zohri to run 30 laps at a speed of 20 km/h on a circular track. This problem involves calculating the circumference of the track and applying the formula Time = Distance / Speed. Suitable for students in Grades 9-12.
