Question 999217
<pre>
           rate         time      distance
Ashley      r           5+1        d
Cody       r+10          5         d

You should be able to understand the meanings of the numbers and variables and how they conform to the description.  Study those for a couple of minutes to understand well.


The time quantities are wordy but well enough specified and are not variable.

Basic rule RT=D lets us make the system of equations:
{{{system(r*6=d,(r+10)*5=d)}}}


Simple substitution, or just equate the two expressions for d.
{{{r*6=(r+10)*5}}}
{{{r*6=5r+50}}}
{{{6r-5r=50}}}
{{{highlight(r=50)}}}
