R*T=D for Rate, Time, Distance.

x = one way distance of the excursion;
48 minutes is 48%2F60=24%2F30=12%2F15=4%2F5 hour

______________speed__________time__________distance
upstream_______3_____________(___)_________x
downstream_____5_____________(___)_________x
TOTAL_________________________4%2F5

Use the equivalent rule equation T=D/R to fill the missing time expressions.

______________speed__________time__________distance
upstream_______3_____________x%2F3____________x
downstream_____5_____________x%2F5____________x
TOTAL_________________________4%2F5

The equation to solve for x should appear easily identified.
