Numeracy question. 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?
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, we can follow these steps:

1. **Determine how much fuel is needed to drive 1500 km**:
   Your car uses 9 litres per 100 km. To find out how many litres you'll need to drive 1500 km, set up a proportion:
   \[
   \text{Fuel needed} = \frac{9 \text{ litres}}{100 \text{ km}} \times 1500 \text{ km} = 135 \text{ litres}.
   \]

2. **Calculate how many tanks of fuel are required**:
   Your fuel tank holds 68 litres. To determine how many full tanks are required for 135 litres of fuel:
   \[
   \text{Number of tanks} = \frac{135 \text{ litres}}{68 \text{ litres}} \approx 1.99.
   \]

Since you cannot use a fraction of a tank, you will need **2 full tanks** of fuel to drive 1500 km.
