Algebra.Com's Answer #526292 by Seutip(231)![]() ![]() You can put this solution on YOUR website! Let:\r \n" ); document.write( "\n" ); document.write( "1/25 - is the part A makes in a minute \n" ); document.write( "1/18 - is the part B makes in a minute\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "43/450 is the part they can do together in a minute.\r \n" ); document.write( "\n" ); document.write( "Now I'll let \"t\" stand for how long they take to do the job together. Then they can do 1/t per hour, so 43/450 = 1/t. Flip the equation, and you get that t = 450/3 or 150.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "They can complete the job together in 150 minutes! :) \n" ); document.write( " |
