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 can break it down into two steps:

1. **Calculate the total amount of fuel needed for 1500 km:**
   - The car uses 9 litres of fuel for every 100 km.
   - To find the total fuel needed for 1500 km, we use the ratio:

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

2. **Determine how many full tanks are needed:**
   - Each tank holds 68 litres.
   - To find how many tanks of fuel are required, divide the total fuel needed by the tank capacity:

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

So, you will need approximately 2 tanks of fuel to drive 1500 km.

Here are some related questions you could explore:
1. How much fuel would you need for a 2000 km journey with the same car?
2. How many kilometers can you drive on a full tank?
3. If fuel costs $1.50 per litre, how much will the 1500 km journey cost in fuel?
4. What would your fuel consumption be if it improved to 8 litres per 100 km?
5. How far can you drive with half a tank of fuel?

**Tip:** Always round up when calculating the number of tanks needed, as you can't fill part of a tank in reality!
