The expression 12g12g12, g gives the number of kilometers a car can travel using ggg liters of gasoline. how far can this car travel on 5 \dfrac125 2 1 5, start fraction, 1, divided by, 2, end fraction liters of gasoline?

The car can travel 66 miles using 5.5 liters of gasoline

Explanation:
We are given that:
The expression 12*g is used to evaluate the number of miles the car can travel using g liters of gasoline.
Therefore:
miles = 12*g

Now, we are given that the liters of gasoline = 5 = 5.5 liters.
To get the number of miles, all we have to do is substitute with the given liters in the above expression as follows:
miles = 12*g
miles = 12 * 5.5
miles = 66 miles

Hope this helps :)
