Question 1162990
.
<pre>

Let d be the distance from home to the store, in miles (one way distance).


The total time traveling both ways is  1{{{1/12}}} hours - {{{1/2}}} of an hour = {{{13/12 - 6/12}}} = {{{7/12}}} of an hour.


Time walking  is  {{{d/5}}}  hours.

Time riding back is  {{{d/30}}}  hours.


Total time equation is


    {{{d/5}}} + {{{d/30}}} = {{{7/12}}}   of an hour.


To solve it, multiply both sides by 60.  You will get


    12d  +  2d  = 35,

    14d         = 35

      d         = {{{35/14}}} = 2.5  miles.    <U>ANSWER</U>

Solved.
