\n" ); document.write( "Wilma can mow the lawn in 3 hours. If Kyle helps her with another mower,
\n" ); document.write( "the lawn can be mowed in 2 hours. How long would it take Kyle if he worked alone?
\n" ); document.write( "~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "Working together, they make  \"1%2F2\"  of the job per hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Wilma makes  \"1%2F3\"  of the job per hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It means that Kyle alone makes  \"1%2F2+-+1%2F3\" = \"3%2F6+-+2%2F6\" = \"1%2F6\"  of the job per hour.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, Kyle will complete the entire job in  \"1%2F%28%281%2F6%29%29\" = 6 hours working alone.    ANSWER\r\n" );

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "On the way, from my exposition, you learned the conception of the rate of work.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You also learned that if you know the combined rate of work of two persons and individual rate of work
\n" ); document.write( "of one of them, then the rate of work of other person is the combined rate minus the known individual rate.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "By knowing it, you can easily solve this and many other similar problems.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It is a standard and typical joint work problem.\r
\n" ); document.write( "
