Car uses 9 L per 100 k’s the tank holds 68 L. How many tanks of fuel will be used to drive 1500km

To determine how many tanks of fuel the car will use to drive 1500 km, we can follow these steps:

1. The car uses **9 liters** per **100 kilometers**.
   
2. To find out how many liters it will use for **1500 kilometers**, we calculate:

\[
\text{Fuel consumption} = \frac{9 \text{ L}}{100 \text{ km}} \times 1500 \text{ km} = 135 \text{ L}
\]

3. The car's fuel tank holds **68 liters**. To find out how many full tanks are needed, divide the total fuel consumption by the tank capacity:

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

Thus, the car will need approximately **2 tanks of fuel** to drive 1500 km.

Here are some related questions:
1. How much fuel is left in the second tank after driving 1500 km?
2. What if the car's fuel consumption changes to 10 L per 100 km? How many tanks then?
3. How many kilometers can the car travel with a full tank?
4. What is the total cost of the fuel for this trip if fuel costs $1.50 per liter?
5. If the car's fuel efficiency improved to 8 L per 100 km, how would the number of tanks change?

**Tip:** Always ensure to check fuel consumption when planning long trips to avoid running out of fuel!
