Question 1056999
Another one of those specific types of constant travel rate problems, so this will be all in variables.


<pre>
                RATE or SPEED     TIME     DISTANCE
GOING TO          r                h        d
RETURNING        r+k               p        d
</pre>

{{{system(h=10,p=7,k=18,r=unknownSpeedGoingto,d=unknownDistanceOneWay)}}}


Question essentially asks for d.
{{{system(rh=d,(r+k)p=d)}}}--------this is the system to solve.
