tutor quick help plz and solution. Ed required 12 hours to lay linoleum tile on his kitchen floor, a job which would take his neighbor Bert only 8 hours to do. They started working together, but after two hours, Bert had to stop and Ed finished the work alone. How many hours more did it take Ed to finish the job?\r
\n" ); document.write( "\n" ); document.write( "Ed required 12 hours to lay linoleum tile on his kitchen floor,
\n" ); document.write( "he does 1/12 of the job in 1 hour\r
\n" ); document.write( "\n" ); document.write( "neighbor Bert only 8 hours to do.
\n" ); document.write( "he does 1/8 of the job in 1 hour\r
\n" ); document.write( "\n" ); document.write( "Together they can do (1/8 +1/12) of the job in 1 hour\r
\n" ); document.write( "\n" ); document.write( "=5/24 \r
\n" ); document.write( "\n" ); document.write( "in 2 hours they do 5*2/24 = 5/12 of the job\r
\n" ); document.write( "\n" ); document.write( "Balance job will be 1- 5/12 = 7/12 of the job\r
\n" ); document.write( "\n" ); document.write( "Now Ed does 1/12 of the job in 1 hour
\n" ); document.write( "he has to do 7/12 of the job \r
\n" ); document.write( "\n" ); document.write( "so he will take (7/12)/(1/12)\r
\n" ); document.write( "\n" ); document.write( "= 7 hours\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
