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 find out how many tanks of fuel you'll use to drive 1500 km, let's follow these steps:

1. **Find the total fuel needed to drive 1500 km:**
   - Your car uses 9 litres per 100 km.
   - For 1500 km:
     \[
     \text{Fuel needed} = \left( \frac{9 \, \text{litres}}{100 \, \text{km}} \right) \times 1500 \, \text{km} = 135 \, \text{litres}
     \]

2. **Determine how many tanks of fuel you'll need:**
   - Your tank holds 68 litres.
   - The number of tanks needed is:
     \[
     \text{Number of tanks} = \frac{135 \, \text{litres}}{68 \, \text{litres per tank}} \approx 1.99
     \]

Since you can't have a fraction of a tank, you will need **2 tanks of fuel** to drive 1500 km.

Here are 5 related questions:
1. How would fuel consumption change if the car used 8 litres per 100 km?
2. How far can you drive on a full tank if the consumption is 9 litres/100 km?
3. How much will it cost to drive 1500 km if fuel costs $1.50 per litre?
4. If the distance was increased to 2000 km, how many tanks of fuel would you need?
5. What is the fuel efficiency in kilometres per litre?

**Tip:** It's always useful to know your car's fuel efficiency in terms of both litres per 100 km and kilometres per litre for easier calculations.
