They start, how many miles apart?
How much faster than the other cyclist is the second cyclist?
They meet in how many hours?


Until you have the needed given values this is the best that can be done:

<pre>
                         SPEED        TIME             DISTANCE

cyclist1                   r            h               rh

cyclist2                  r+k           h              (r+k)h

distance to be closed                                    d
</pre>
{{{hr+h(r+k)=d}}}

{{{hr+hr+hk=d}}}

{{{2hr=d-hk}}}

{{{r=(d-hk)/(2h)}}}
