Question 1201875
If opposite directions East and West, then let speeds of each be e and w.
110 miles apart after 2 hours travel time.

You were not given which is the slower or faster car.  Only that they go in
opposite directions, and if assuming they begin at same time and from same 
starting point then

<pre>
          SPEED      TIME         DISTANCE

EAST        e          2          (e)(2)

WEST        w          2          (w)(2)

TOTAL              same 2           110
</pre>
{{{2e+2w=110}}}

{{{e+w=110/2}}}

{{{e+w=55}}}
This is about as much as can be done.
