Let's go through the problems in the image one by one.

### Problem 5
**Statement:** Find the length of the road connecting Kecamatan C and Kecamatan H.

**Solution:**
From the image, it appears that the path connecting C and H is a straight line, which can be interpreted as the hypotenuse of a right triangle. If the distance \( CD = 40 \, \text{km} \) is given and knowing that \( DE = 15 \, \text{km} \), we can use the Pythagorean theorem to find the length \( CH \).

Let's denote:
- \( CD = 40 \, \text{km} \)
- \( DH = \sqrt{(CD)^2 + (DE)^2} \)
- \( DE = 15 \, \text{km} \)

Plugging in the values:
\[ CH = \sqrt{(40)^2 + (15)^2} = \sqrt{1600 + 225} = \sqrt{1825} = 43 \, \text{km} \]

This matches with option E.

### Problem 6
**Statement:** Find the shortest distance from Kecamatan C to Kecamatan E by car.

**Solution:**
The shortest distance will follow the straight path from C to E, since the other path involves a curved route.

Given that the coordinate plane distance between \( C \) and \( E \) is equivalent to moving diagonally across a right triangle formed by distances:
- \( CE = \sqrt{(15)^2 + (15)^2} = \sqrt{450} = 15\sqrt{2} \, \text{km} \)

This matches with option C.

### Problem 7
**Statement:** Calculate the time Andre needs to travel from Kecamatan G to D, passing through E and F.

**Solution:**
1. **Total Distance Calculation:**
   - \( GE \) is a quarter circle.
   - \( EF \) is a straight line.
   - \( FD \) is another straight line.

2. **Speed Calculation:**
   - Average speed on the road is 50 km/h.
   - Speed on the toll road is 30 km/h.

3. **Time Calculation:**
   This requires more detailed information on the specific lengths which needs to be extracted from the figure.

### Problem 8
**Statement:** Determine when Hadi should start driving from Kecamatan G to meet Badu at F exactly when Badu arrives.

**Solution:**
1. **Speed Comparison:**
   - Speed of Hadi: \( 30 \, \text{km/h} \).
   - Speed of Badu: \( 15\sqrt{5} \, \text{km/h} \).

2. **Distance and Time Synchronization:**
   - Badu starts at 08:00 AM.
   - Calculate the meeting time at F.

We'd need to set up equations using the distances and speeds to find the exact starting time for Hadi.

### Tip:
Always break down the problem into smaller segments and solve step-by-step to avoid confusion, especially when dealing with mixed types of paths like straight lines and curves.

The image contains math problems involving distances between different districts (Kecamatan) in a city, with a combination of straight and curved paths.

This problem involves calculating distances between districts in a city map using the Pythagorean theorem, understanding speed and time for different types of roads, and applying distance formulas in coordinate geometry.
