R*T=D for Rate, Time, Distance.
x = one way distance of the excursion;
48 minutes is hour
______________speed__________time__________distance
upstream_______3_____________(___)_________x
downstream_____5_____________(___)_________x
TOTAL_________________________
Use the equivalent rule equation T=D/R to fill the missing time expressions.
______________speed__________time__________distance
upstream_______3_________________________x
downstream_____5_________________________x
TOTAL_________________________
The equation to solve for x should appear easily identified.
