Answer:
25 gallons
Step-by-step explanation:
Given
135 miles to 5 gallons
Required
Determine the number of gallons for 675 miles
From the question, number of miles is directly proportional to number of gallons:
So, we have:
[tex]135\ miles = 5\ gallons[/tex]
and
[tex]675\ miles = x[/tex]
Where x represents the number of gallons for 675 miles
Cross Multiply:
[tex]135 * x = 675 * 5[/tex]
[tex]135x = 3375[/tex]
Make x the subject
[tex]x = 3375/135[/tex]
[tex]x = 25[/tex]
Hence, the car needs 25 gallons
