To solve the problem, let's break it down step by step.

### Information Given:
- Fuel consumption: 9 litres per 100 km.
- Tank capacity: 68 litres.
- Distance to drive: 1500 km.

### Step 1: Calculate the total amount of fuel needed for 1500 km.
We know that the car uses 9 litres per 100 km. So, to calculate the total fuel needed for 1500 km:

\[
\text{Fuel needed} = \left( \frac{9 \, \text{litres}}{100 \, \text{km}} \right) \times 1500 \, \text{km} = \frac{9 \times 1500}{100} = 135 \, \text{litres}.
\]

### Step 2: Calculate how many full tanks are needed.
Each tank holds 68 litres, so the number of tanks required is:

\[
\text{Number of tanks} = \frac{135 \, \text{litres}}{68 \, \text{litres}} \approx 1.985.
\]

Since you can't fill a fraction of a tank, you'll need 2 full tanks of fuel to drive 1500 km.

### Answer: **2 tanks of fuel are required.**

2. If you improved fuel efficiency to 7 litres per 100 km, how many tanks would you need for 1500 km?
3. What is the maximum distance you can drive on one full tank with your current fuel consumption?
4. How much fuel would you save on a 1500 km trip if fuel consumption decreased by 1 litre per 100 km?
5. How many kilometers could you drive with half a tank?

**Tip:** Always round up the number of tanks required, as you can't refill part of a tank.

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?

Learn how to calculate the number of fuel tanks needed to drive 1500 km, given a fuel consumption rate of 9 litres per 100 km and a tank capacity of 68 litres. This problem involves basic arithmetic and proportion calculations, suitable for students in Grades 5-7.
