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 calculate how many tanks of fuel will be needed to drive 1500 km, follow these steps:

1. **Calculate total fuel needed for 1500 km**:
   - The car uses 9 litres per 100 km.
   - For 1500 km: 
   
   \[
   \text{Fuel required} = \frac{9 \, \text{litres}}{100 \, \text{km}} \times 1500 \, \text{km} = 135 \, \text{litres}
   \]

2. **Determine how many tanks of fuel are required**:
   - The car's tank holds 68 litres.
   - To find how many tanks are needed, divide the total fuel required by the tank's capacity:
   
   \[
   \text{Number of tanks} = \frac{135 \, \text{litres}}{68 \, \text{litres/tank}} = 1.985 \, \text{tanks}
   \]

Since you can't use a fraction of a tank, you'll need 2 full tanks of fuel to drive 1500 km.
