Algebra.Com's Answer #136538 by nerdybill(7384) You can put this solution on YOUR website! You will be applying the \"distance formula\": \n" ); document.write( "d = rt \n" ); document.write( "where \n" ); document.write( "d is distance \n" ); document.write( "r is rate or speed \n" ); document.write( "t is time \n" ); document.write( ". \n" ); document.write( "Let x = speed of the boat \n" ); document.write( "then \n" ); document.write( "\"distance traveled downstream\" = \"distance traveled upstream) \n" ); document.write( "4(x+6) = 5(x-6) \n" ); document.write( "4x + 24 = 5x - 30 \n" ); document.write( "24 = x - 30 \n" ); document.write( "54 mph = x \n" ); document.write( " |
