Question 1204939
<br>
Using logical reasoning, if the paddling speed PLUS the current speed is 40 and the paddling speed MINUS the current speed is 26, then the paddling speed must be halfway between 40 and 26: (40+26)/2 = 66/2 = 33.  Then the current speed is the difference between the paddling speed and either the upstream or downstream speed: 40-33 = 7, or 33-26 = 7.<br>
ANSWER: 7 m/min<br>
