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

To calculate how many tanks of fuel you'll use to drive 1500 km, follow these steps:

1. **Fuel consumption per 100 km**:  
   You use 9 litres of fuel for every 100 km.

2. **Total fuel needed for 1500 km**:  
   \[
   \text{Fuel needed} = \left( \frac{9 \text{ litres}}{100 \text{ km}} \right) \times 1500 \text{ km} = 135 \text{ litres}
   \]

3. **Number of tanks required**:  
   The fuel tank holds 68 litres. So, divide the total fuel needed by the tank capacity:
   \[
   \text{Number of tanks} = \frac{135 \text{ litres}}{68 \text{ litres/tank}} \approx 1.99 \text{ tanks}
   \]

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