Algebra.Com's Answer #140265 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Connie can type 600 words in 5 minutes less than it takes katie to type 600 words. If connie types at a rate of 20 words per minute faster than katie types, find the typing rate of each woman. \n" ); document.write( "----------------- \n" ); document.write( "Katie DATA: \n" ); document.write( "time = x min/600 wds ; rate = 600 wds/x min \n" ); document.write( "------------------------------------------- \n" ); document.write( "Connie DATA: \n" ); document.write( "time = (x-5) min/600 wds ; rate = 600wds/(x-5)min \n" ); document.write( "------------------------------------------------------- \n" ); document.write( "Equations: \n" ); document.write( "Connie rate - Katie rate= 20 \n" ); document.write( "600/(x-5) - (600/x) = 20 \n" ); document.write( "3000 = 20x(x-5) \n" ); document.write( "x(x-5)= 150 \n" ); document.write( "x^2 -5x - 150 = 0 \n" ); document.write( "(x-15)(x+10) = 0 \n" ); document.write( "Positive solution: \n" ); document.write( "x = 15 minutes (time for Katie to type 600 wds). \n" ); document.write( "x-5 = 10 minutes (time for Connie to type 600 wds) \n" ); document.write( "===================================================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
