\r\n" );
document.write( "David's dishwashing rate is 1 sinkful per 45 minutes or\r\n" );

\r\n" );
document.write( "Todd's dishwashing rate is 1 sinkful per 30 minutes or\r\n" );
document.write( "\r\n" );

\n" ); document.write( "

\r\n" );
document.write( "Suppose it takes them x minutes working together.\r\n" );
document.write( "\r\n" );
document.write( "Then their combined dishwashing rate is 1 sinkful per x minutes or\r\n" );
document.write( "\r\n" );
