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 problem, we need to calculate the total amount of fuel needed to drive 1500 kilometers and then determine how many full tanks of fuel will be required.

### Step 1: Calculate the total fuel needed
We know the car consumes 9 liters per 100 kilometers. To find the fuel required for 1500 kilometers, we can set up a proportion:

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

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

### Step 2: Determine how many tanks are required
Each tank holds 68 liters. To find how many full tanks are needed, we divide the total fuel required by the capacity of the tank:

\[
\text{Number of tanks} = \frac{135 \, \text{liters}}{68 \, \text{liters/tank}} \approx 1.99 \, \text{tanks}
\]

Since you can't use a fraction of a tank, you will need **2 full tanks** to cover the 1500 kilometers.
