natalie and lindsey can fold 300 chairs in 10 minutes. How long does it take natalie to fold 300 chairs if she works twice as fast?

\r\n" );
document.write( "Suppose Natalie can do 1 folding job in x minutea. Then her rate is\r\n" );
document.write( "1 folding job per x minutes or \"1_folding_job%2Fx_min\" or \"1%2Fx\"\"folding_job%2Fminute\"\r\n" );
document.write( "\r\n" );
document.write( "Natalie works twice as fast as Lindsey, so Lindsey takes twice as\r\n" );
document.write( "long as natalie so her rate is 1 folding job per 2x minutes or\r\n" );
document.write( "\"1_folding_job%2F%282x_min%29\" or \"1%2F%282x%29\"\"folding_job%2Fminute\".\r\n" );
