<PRE><B>Question 32134</B>
Train Data:
 distance=120km; time=x hrs; 
Since rate=distance/time, rate=120/x
Car Data:
 distance=600-120=480km; time=8-x; rate=?480/(8-x)
EQUATION:
There is not enough information to write an equation.
Check again the statement of this problem in the text.
Maybe post again.
Cheers,
