<PRE><B>Question 676634</B>
Distance(d) equals Rate(r) times Time(t) or d=rt; r=d/t and t=d/r
They meet when they are both the same distance from Chicago.  Let t=time it takes for that to happen
distance that Rocky is from Chi in t hours=315-60t
distance that Sally is from Chi in t hours= 115t

Soooooo
315-60t=115t
175t=315
t=1.8 hrs

CK
in 1.8 hrs, Rocky has traveled 60*1.8=108 mi  and is 315-108=207 mi from Chicago
in 1.8 hrs, Sally has traveled 115*1.8 mi=207 mi and is 207 mi from Chicago

Hope this helps---ptaylor
