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

Answer:

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

Step-by-step 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:

$\frac{12}{144} = \frac{x+6}{240}$

Multiply 240 to both sides of an equation we have;

$\frac{12}{144} \times 240 = x+6$

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.
