____________________rate______________time_________________distance
Group one___________r+2.5_____________200__________________{{{(r+2.5)*200}}}
Group two____________r________________200__________________{{{r*200}}}
Total______________________________________________________1050


Use the sum of their distances.  The two groups meet when the sum of their distances traveled is 1050 miles.  Setup the proper equation and solve for r and r+2.5.</PRE>
