Question

12 gallons of gas to travel 144 miles. Six gallons in the tank how much more will she need to travel 240

Answer 1

14 gallons of a gas more will she need to travel 240 miles.

Explanation:

Proportion states that the two fractions or ratios are equal.

Let x represents the more gallons will she need to travel 240 miles.

As per the statement:

12 gallons of gas to travel 144 miles. Six gallons in the tank.

Then;

By definition of proportion:

`(12)/(144) = (x+6)/(240)`

Multiply 240 to both sides of an equation we have;

`(12)/(144) * 240 = x+6`

Simplify:

`20 = x+6`

Subtract 6 from both sides we get;

`14 = x`

Therefore, 14 gallons of a gas more will she need to travel 240 miles.
