Question 1057674
Uniform Travel Rate Rule is RT=D.

<pre>
              RATE      TIME      DISTANCE
JAMES         r+5
PAT           r
Total                    5          130
</pre>

Two unknown variables are needed; or maybe just one?



<pre>
              RATE      TIME      DISTANCE
JAMES         r+5        j        (r+5)j
PAT           r          p         rp
Total                    5          130
</pre>
Three variables but only two equations:
{{{system(j+p=5,(r+5)j+rp=130)}}}
Mostly infinite results possible for r.
