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 determine how many tanks of fuel you'll use to drive 1,500 km, we can follow these steps:

1. **Calculate fuel consumption for 1,500 km**:  
   Your car consumes 9 litres of petrol per 100 km. So, for 1,500 km:
   \[
   \text{Fuel consumed} = \frac{9 \text{ litres}}{100 \text{ km}} \times 1500 \text{ km} = 135 \text{ litres}.
   \]

2. **Calculate the number of tanks needed**:  
   Your tank holds 68 litres. So, to find how many full tanks you will need:
   \[
   \text{Number of tanks} = \frac{135 \text{ litres}}{68 \text{ litres/tank}} \approx 1.985 \text{ tanks}.
   \]

Therefore, you'll need approximately **2 full tanks** of petrol to drive 1,500 km.
