\r\n" );
document.write( "Let J be Jo's rate of work.\r\n" );
document.write( "\r\n" );
document.write( "Then Ralph's rate of work is twice of it, and is equal to 2J.\r\n" );
document.write( "\r\n" );
document.write( "When they work together, their combined rate of work is the sum of individual rates, i.e. J + 2J = 3J.\r\n" );
document.write( "\r\n" );
document.write( "We are given that 3J = .\r\n" );
document.write( "\r\n" );
document.write( "Hence, J = .\r\n" );
document.write( "\r\n" );
document.write( "It means that it takes 18 hours for Jo to complete the job working alone.\r\n" );
