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 solve this problem, we can break it down into steps:

1. **Determine how many litres of petrol you will need to drive 1500 km:**

   The car uses 9 litres per 100 km. So, for 1500 km:
   \[
   \text{Total litres} = \left( \frac{9}{100} \right) \times 1500 = 135 \text{ litres}
   \]

2. **Determine how many full tanks of petrol are needed:**

   The car's tank holds 68 litres. So, to find how many tanks are needed for 135 litres:
   \[
   \text{Number of tanks} = \frac{135}{68} \approx 1.99
   \]

So, you'll need approximately **2 full tanks** to drive 1500 km.
