Step-by-step explanation:
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
or 5.5 liters of gasoline = x= ?
Now we can find this by substituting g=
in the the above equation representing number of kilometers traveled by the car.
Number of km's traveled by a car using
liters of gasoline = 12 (
)
x = 12 (5.5)
x= 66 km
So, the car travels 66km in 5.5 liters of gasoline
