<PRE><B>Question 1142998</B>
One way is to set up a proportion:

{{{ matrix(1,3, 130 / 4, &quot; = &quot;, x / 6.7) }}}&lt;br&gt;

{{{ matrix(1,5, &quot;x&quot;, &quot; = &quot;, 6.7 * ( 130 / 4 ), &quot; = &quot;, &quot; 217.75&quot;) }}}&lt;br&gt;

---------

Another way, which is basically the same as above but with two distinct steps, is to compute the fuel economy (miles per gallon) of the truck, then figure out how far the truck can travel on 6.7 gallons of diesel fuel:&lt;br&gt;

MPG = 130mi/4gal = 32.5mi/gal  &lt;br&gt;

The truck can therefore travel  32.5mi/gal * 6.7gal = 217.75 mi on 6.7 gal of diesel fuel.&lt;br&gt;
