ok. so when he paddles upstream, he's going against the current. If we let x represent his paddling rate in still water and let y represent the rate of the current. When he goes upstream the equation is X-Y=3 and when he goes downstream X+Y=8 when we combine the two equations the Y's cancel out and you get 2X=11. x = 5.5 then you plug 5.5 into one of the equation for x and you find y
