Rate unit is \"TANK%2FMINUTES\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Rate for both taps open is the sum of their rates.
\n" ); document.write( "\"1%2F30%2B1%2F90\"\r
\n" ); document.write( "\n" ); document.write( "\"3%2F30%2B1%2F90\"\r
\n" ); document.write( "\n" ); document.write( "\"4%2F90\"\r
\n" ); document.write( "\n" ); document.write( "\"2%2F45\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The time in minutes to fill the one tank is \"45%2F2=22%261%2F2\" minutes.
