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 need for a 1500 km drive, follow these steps:

1. **Fuel consumption per kilometer**:
   Your car uses 9 liters of fuel for every 100 kilometers, so it uses:
   \[
   \frac{9 \, \text{liters}}{100 \, \text{km}} = 0.09 \, \text{liters per kilometer}
   \]

2. **Total fuel required for 1500 km**:
   Multiply the fuel usage per kilometer by the total distance (1500 km):
   \[
   1500 \, \text{km} \times 0.09 \, \text{liters per km} = 135 \, \text{liters}
   \]

3. **Number of tanks required**:
   Your car's tank holds 68 liters, so the number of tanks required is:
   \[
   \frac{135 \, \text{liters}}{68 \, \text{liters per tank}} \approx 1.99 \, \text{tanks}
   \]
   You will need approximately **2 tanks of fuel** to drive 1500 km.
