gasoline consumption problem suppose that the gas tank of a car holds 12 gallons and that the car uses 1/ 20 of a gallon per mile .let x be the nuber of miles the car has gone since the tank was filled?

car holds 12 gallons
1/20 gallon/mile
12*20 = 240 miles possible
what is this question asking?

This question is asking how many miles the car has gone since the gas tank was last filled. It gives the information that the gas tank holds 12 gallons and that the car uses 1/20 of a gallon per mile. To solve this problem, we can use the formula:

miles = gallons * (1 / gallons_per_mile)

In this case, we plug in the given values:

miles = 12 gallons * (1 / (1/20 gallon/mile))

Simplifying, we get:

miles = 12 * 20

So the car can go a maximum of 240 miles before it runs out of gas.
