\n" ); document.write( "It is a standard and typical joint work problem.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "When you solve such a problem (as any other Math problem), it is important to get not only correct answer (number).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It is also important to get the solution, presented in clear, logical and correct form.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It is why I am writing my solution after the solution of the other tutor.\r

document.write( "    Ana does   of the job in hour.  In each hour.  It is her rate of job.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    Working together, Ana and Beth do   of the job per hour. It is their combined rate of work.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    Then it is clear that the Beth's individual rate of work is the difference   -  =  -  =  of the job per hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    It means that Beth can complete the job in  = 7.5 hours working alone.\r\n" );
