Jessica can type a manuscript in 8 hours. Heather can type the same manuscript in 13 hours. If they work together, how long will it take to process the manuscript?\r
\n" ); document.write( "\n" ); document.write( "Jessica can type a manuscript in 8 hours.\r
\n" ); document.write( "\n" ); document.write( "she can do 1/8 of the job in 1 hour\r
\n" ); document.write( "\n" ); document.write( " Heather can type the same manuscript in 13 hours. \r
\n" ); document.write( "\n" ); document.write( "he can do 1/13 of the job in 1 hour\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Together they can do\r
\n" ); document.write( "\n" ); document.write( "1/8 + 1/13 of the job in 1 hour\r
\n" ); document.write( "\n" ); document.write( "(13+8)/13*8 of the job in 1 hour\r
\n" ); document.write( "\n" ); document.write( "21/104 \r
\n" ); document.write( "\n" ); document.write( "so they will take 104/21 hours to complete the job together\r
\n" ); document.write( "\n" ); document.write( "=4.95 hours
\n" ); document.write( " \n" ); document.write( "
