Let's call the distance that he paddles one way  = D....note that the distances going and coming are the same  ...so....

 

And  Distance  / Rate  = time  [ In hours]...so...

 

D / 3  +  D / 2  =  2.5    simplify

 

D [  2 + 3 ] / 6  = 2.5   multiply both sides by 6

 

D [ 5 ]  =  15      divide both sides by  5

 

D  = 3 km

 

 

 

cool cool cool
