Let's use the formula for direct variation:
distance = k * gasoline
where k is the constant of proportionality. We can find k by using the values given:
504 = k * 18
Solving for k:
k = 504/18 = 28
Now we can use this value of k to answer the question. If the car has 26 gallons of gasoline:
distance = k * gasoline = 28 * 26 = 728 miles
Therefore, the car can travel 728 miles with 26 gallons of gasoline.
Suppose that the distance a car travels varies directly with the amount of gasoline it uses. A certain car uses
18
gallons of gasoline to travel
504
miles. How many miles can the car travel if it has
26
gallons of gasoline?
