To solve the problem in the image, we need to calculate how many full tanks of fuel will be required for a car to drive 1500 km, given the following information:

- Fuel consumption is 9 litres per 100 km.
- The car's fuel tank holds 68 litres.

### Step 1: Calculate total fuel needed for 1500 km
First, we calculate the total amount of fuel required to travel 1500 km using the car's fuel consumption rate:
\[
\text{Fuel consumption} = \frac{9 \, \text{litres}}{100 \, \text{km}}
\]
\[
\text{Fuel required for 1500 km} = 1500 \times \frac{9}{100} = 135 \, \text{litres}
\]

### Step 2: Calculate how many full tanks are needed
Now, divide the total fuel required by the capacity of the tank:
\[
\text{Number of tanks} = \frac{135 \, \text{litres}}{68 \, \text{litres per tank}} \approx 1.985 \, \text{tanks}
\]

### Step 3: Round to the nearest whole number
Since we need a whole number of tanks, we round 1.985 up to 2.

Thus, you will need **2 full tanks** of fuel to drive 1500 km.

Here are 5 related questions for further practice:
1. What if the car's consumption was 10 litres per 100 km? How many tanks for 1500 km?
2. How many litres would be used for a 2000 km drive?
3. How much distance can be covered with half a tank of fuel?
4. If the tank size increased to 75 litres, how would that affect the number of tanks?
5. How many kilometres could you drive with 3 full tanks of fuel?

**Tip:** Always check units when working with fuel consumption and distances to ensure accurate conversions!

Your car petrol usage is 9 litres / 100 km. Your tank holds 68 litres. How many tanks of fuel will you use to drive 1500 km?
