Question 1197415
.
A particular hybrid car travels approximately 318 mi on 6 gallon of gas. Find the amount of gas required for a 901-mi trip.
~~~~~~~~~~~~~~


<pre>
It is a typical problem on proportion.


After reading the problem, you write a proportion

    {{{318/6}}} = {{{901/x}}},


saying that the mileage per gallon is the same in both cases (remains unchangeable).


From the proportion, you find

    x = {{{(6*901)/318}}} = 17.


So, having 17 gallons in your gasoline tank, you may go to the road.
</pre>

Solved.
