You can put this solution on YOUR website! _____________speed__________time_________distance
Downriver_____X+Y____________1.5__________10.5
Upriver_______X-Y____________3.5__________10.5
RT=D the basic uniform rates travel relationship. R for speed, T for time, D for distance. You have two equations for your data.
