\n" ); document.write( "If Craig can paint a house in 18 hours and when working with John
\n" ); document.write( "can complete the job in 10 hours.
\n" ); document.write( "How long should it take John to complete the job working alone?
\n" ); document.write( "~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "The combined rate of work of two workers is    of the job per hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The rate of work of one of them (Craig) is    of the job per hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "HENCE, the rate of work of the other worker (of John) is the difference\r\n" );
document.write( "\r\n" );
document.write( "     -  =  -  =  = .\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It means that John will complete the job in   = 22.5 hours, working alone.     ANSWER\r\n" );

\n" ); document.write( "\n" ); document.write( "Solved.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "On the way, from my solution you learned about rate of work.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You also learned, that when combined rate of work is given,
\n" ); document.write( "and the rate of work of one participant is known,
\n" ); document.write( "then the rate of work of the other participant is simply the difference of two rates.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-----------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It is a standard and typical joint work problem.\r
\n" ); document.write( "
