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?
Round your answer to the nearest whole number.

To find out how many tanks of fuel you'll need to drive 1500 km, follow these steps:

1. **Calculate how much fuel is needed for 1500 km**:
   Your car uses 9 litres for every 100 km. So, the total amount of fuel required for 1500 km is:

   \[
   \text{Fuel needed} = \frac{9 \, \text{litres}}{100 \, \text{km}} \times 1500 \, \text{km} = 135 \, \text{litres}
   \]

2. **Determine how many tanks of fuel you need**:
   Each tank holds 68 litres. So, the number of tanks required is:

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

   Rounded to the nearest whole number, you will need **2 tanks** of fuel.
