Algebra.Com's Answer #83548 by stanbon(75887) ![]() You can put this solution on YOUR website! Sean paddled upstream 3 hours to camp. The next day he makes the return trip downstream in 1 hour. Sean can paddled 2 mph in still water. How fast is the current? \n" ); document.write( "----------------- \n" ); document.write( "Let the current speed be \"c\". \n" ); document.write( "------------------- \n" ); document.write( "Upstream DATA: \n" ); document.write( "Time = 3 hrs ; Rate = 2-c mph ; Distance = rt = 3(2-c) miles \n" ); document.write( "----------------- \n" ); document.write( "Downstream DATA: \n" ); document.write( "Time = 1 hr ; Rate = (2+c) mph ; Distance = rt = 2+c miles \n" ); document.write( "----------------- \n" ); document.write( "EQUATION: \n" ); document.write( "distance up = distance down \n" ); document.write( "6-3c = 2+c \n" ); document.write( "4c = 4 \n" ); document.write( "c = 1 mph (speed of the current) \n" ); document.write( "============== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
