Substitute in 5 1/2 for g in the expression : 12g=12(5 1/2)=66

So, this car can go 66 kilometers on 5 1/2 liters of gasoline.

Answer:

66 km

Step-by-step explanation:

Given that

Number of km's traveled by a car using g liters of gasoline  = 12g

Number of gallons of gas required to travel 12g kilometers = g

We have to find

How far this car can travel using [tex]5 \frac{1}{2}[/tex] or 5.5 liters of gasoline = x= ?

Now we can find this by substituting g= [tex]5 \frac{1}{2}[/tex] in the the above equation representing number of kilometers traveled by the car.

Number of km's traveled by a car using [tex]5 \frac{1}{2}[/tex] liters of gasoline = 12 ([tex]5 \frac{1}{2}[/tex])

x = 12 (5.5)

x= 66 km

So, the car travels 66km in 5.5 liters of gasoline
