Question 1163452
.
<pre>

Let d be one way distance.


Then you have this "time" equation


    {{{d/4}}} + {{{d/20}}} = 8  hours.


The terms in the left side are the time intervals walking/riding in each direction.


To solve the equation, multiply both sides by 20.  You will get

    5d + d = 8*20

    6d     = 160

     d     = 160/6 = 26 {{{2/3}}} miles = 26.67 miles.    <U>ANSWER</U>
