Answer 2

Solving the Problem Using an Equation

To solve this problem, we can use the equation:

fuel consumption = (fuel used) / (time traveled)

Given that the car uses 18 liters of fuel in 2 hours, we can use this information to find out how long it will take for the car to use 45 liters of fuel.

Let's calculate the time it will take for the car to use 45 liters of fuel.

Calculating the Time

Using the formula:

time = (fuel used) / (fuel consumption)

We can calculate the time as follows:

time = 45 liters / (18 liters / 2 hours)

time = 45 liters / 9 liters/hour

time = 5 hours

So, the car will be able to travel for 5 hours with 45 liters of fuel.
