The problem describes a Ferris wheel, the Melbourne Star, rotating clockwise at a constant speed, taking 28 minutes to complete one full rotation. A person is at point \( C \) at 08:30 and the question is asking at what time they will arrive at point \( B \).

Here’s how we can solve this:

### Step 1: Understand the geometry
- The Ferris wheel has 8 labeled points (A, B, C, D, E, F, G, and H).
- Since it takes 28 minutes to make a full rotation, the time to travel from one point to the next is:
  \[
  \text{Time per segment} = \frac{28}{8} = 3.5 \text{ minutes}
  \]

### Step 2: Calculate the time to move from \( C \) to \( B \)
- The Ferris wheel is moving clockwise, so to go from point \( C \) to point \( B \), it is moving through 1 segment. 
- The time to move between adjacent points is 3.5 minutes.

### Step 3: Add this time to the starting time
- The person starts at 08:30. Adding 3.5 minutes:
  \[
  08:30 + 3.5 \text{ minutes} = 08:33.5
  \]

Thus, the person will reach point \( B \) at approximately **08:33 and 30 seconds**. The closest answer given is **08:36**.

Would you like to go into more details about any part of the explanation? Here are some related questions for further understanding:

1. How would the solution change if the wheel took 20 minutes for a full rotation?
2. What would the answer be if the person started at point \( D \) instead of point \( C \)?
3. How can we generalize this problem for any number of segments on the wheel?
4. What would happen if the Ferris wheel rotated counterclockwise?
5. How does the height of the Ferris wheel affect the time calculation?

**Tip:** When dealing with Ferris wheels or other circular motions, dividing the rotation period by the number of segments is key to solving time-related problems!
