\n" ); document.write( "Tap A can fill the tank in 6 minutes and tap B in 3 minutes. how long will both tapes take to fill the tank if opened at the same time.
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "Tap A fills  \"1%2F6\"  of the tank volume in one minute when works alone. Its rate is  \"1%2F6\"  of the tank volume per minute.\r\n" );
document.write( "\r\n" );
document.write( "Tap B fills  \"1%2F3\"  of the tank volume in one minute when works alone. Its rate is  \"1%2F6\" of the tank volume per minute.\r\n" );
document.write( "\r\n" );
document.write( "When both taps work together, they fill  \"1%2F6+%2B+1%2F3\"  of the tank volume per minute.\r\n" );
document.write( "In other words, their combined rate is the sum of their individual rates  \"1%2F6+%2B+1%2F3\" = \"1%2F6+%2B+2%2F6\" = \"3%2F6\" = \"1%2F2\".\r\n" );
document.write( "\r\n" );
document.write( "It means that two taps fill  \"1%2F2\"  of the tank volume per minutes.\r\n" );
document.write( "\r\n" );
document.write( "Now it is clear that it takes 2 minutes for both taps to fill the tank.\r\n" );
document.write( "\r\n" );
document.write( "Answer.  It will take 2 minutes for both taps to fill the tank.\r\n" );
document.write( "\r\n" );
