If a car travel 12 miles on 0.3 gallon of gas. How far can it travel on 1gallon?

1 gallon (12 miles/0.3 gal) = 120/3

= 40 miles

12/0.3 = x/1

0.3x = 12

x = 40

To calculate how far the car can travel on 1 gallon of gas, we can use the concept of proportion.

Given:
Car travels 12 miles on 0.3 gallon of gas.

Let's set up the proportion:

12 miles / 0.3 gallon = x miles / 1 gallon

Now, we can solve for x:

Cross multiplying, we get:

12 miles * 1 gallon = 0.3 gallon * x miles

12 miles = 0.3x miles

Divide both sides of the equation by 0.3:

(12 miles) / 0.3 = (0.3x miles) / 0.3

40 miles = x

Therefore, the car can travel 40 miles on 1 gallon of gas.

To determine how far the car can travel on 1 gallon of gas, we can use proportions.

Let's set up the proportion:
12 miles is to 0.3 gallon as x miles is to 1 gallon.

We can solve this proportion by cross-multiplication. Cross-multiplying means multiplying the values diagonally across from each other.

12 miles * 1 gallon = 0.3 gallon * x miles

Simplifying this equation, we get:

12 = 0.3x

To find the value of x, we can divide both sides of the equation by 0.3:

12 / 0.3 = x

x = 40

Therefore, the car can travel 40 miles on 1 gallon of gas.
