Let's analyze and solve the questions from the image you uploaded:

---

### 1. Dina's Coffee Business
- **Problem**: Dina sells iced coffee made from high-quality ingredients. Each cup contains 1.5 liters. Last week she sold 7 cups, and this week she sold 5. The question asks for the volume of coffee per cup.
- **Answer**: Since the volume of coffee per cup is given as 1.5 liters, the volume per cup is 1.5 liters.

### 2. Pak Pandrya's Storage Basket
- **Problem**: Pak Pandrya has a large storage basket for sports balls (futsal, volleyball, basketball). The basket has dimensions (length, width, and height), and the task is to calculate the volume, which is the product of these dimensions.
- **Answer**: The formula for volume is:
  \[
  \text{Volume} = \text{Length} \times \text{Width} \times \text{Height}
  \]
  To calculate this, the values for the dimensions are needed, which seem to be left blank in the problem.

### 3. Water Leakage from the Tap
- **Problem**: A tap at a school leaks water continuously. If the leak rate is \( x \) liters per second and the tap runs for 10 hours, how many seconds does 1 hour correspond to?
- **Solution**: 
  - Convert 1 hour into seconds:
    \[
    1 \, \text{hour} = 3600 \, \text{seconds}
    \]
  - Therefore, 1 hour of leakage corresponds to 3600 seconds.

### 4. Aircraft Viewing Distance
- **Problem**: The distance at which an aircraft is visible is described by the formula involving \( d \), the distance in meters, and \( h \), the height of the aircraft in meters. If the aircraft is at 3600 meters, find the distance \( d \).
- **Solution**: The formula likely follows a line-of-sight calculation. The formula is given as:
  \[
  d = \sqrt{2Rh}
  \]
  where \( R \) is the Earth's radius, approximately 6371 km (converted to meters). Plug in \( h = 3600 \) meters to calculate \( d \).

### 5. Population Growth
- **Problem**: The population of city B was 200,000 in 2022, with a growth rate of 4%. The population is expected to grow to 800,000. How many years will this take?
- **Solution**:
  - The formula for population growth is:
    \[
    P_t = P_0 (1 + r)^t
    \]
    Where:
    - \( P_t = 800,000 \)
    - \( P_0 = 200,000 \)
    - \( r = 0.04 \)
    - \( t \) is the unknown (number of years).
  - Using logarithms to solve for \( t \):
    \[
    \log(800,000) = \log(200,000) + t \log(1.04)
    \]
    Calculate to find \( t \).

Do you want further details or explanations for any specific problem?

Here are some related questions for further practice:

1. How would you calculate the total volume of coffee Dina sold last week and this week combined?
2. If Pak Pandrya's basket had specific dimensions, how would the volume change if one dimension doubled?
3. What would the total water wasted be if the tap leaked for an entire day?
4. If the height of the aircraft increased, how would that affect the viewing distance \( d \)?
5. What if the population growth rate was 3% instead of 4%, how would that affect the number of years to reach 800,000?

**Tip**: For word problems, breaking them down step by step helps clarify which formulas or concepts to apply.
