<PRE><B>Question 754517</B>
The question is, how many miles from A to B?
Assume the distance although unknown, is d.


DIRECTION____________rate____________time______________distance
A to B_______________8_______________(___)_____________d
B to A_______________4_______________(___)_____________d
TOTAL________________________________3_________________2d


The unfilled information in the chart should be determined or found expressible enough to fillin the entry in the chart.  (The time information).


DIRECTION____________rate____________time______________distance
A to B_______________8_______________(d/8)_____________d
B to A_______________4_______________(d/4)_____________d
TOTAL________________________________3_________________2d


YOU SEE a summation of terms for time equaling the total time of 3 hours.  THAT gives you a useful equation in order to solve for d.  </PRE>
