One pipe can fill a tank in 0.8 hours
\n" ); document.write( "and another pipe can fill the tank in 1.2
\n" ); document.write( "hours. If both pipes are used, how long
\n" ); document.write( "will it take to fill the tank? Round to 2
\n" ); document.write( "decimal places.
\n" ); document.write( "------------
\n" ); document.write( "0.8*1.2/(0.8 + 1.2) hours
\n" ); document.write( "= 0.96/2 hours
\n" ); document.write( "= 0.48 hours
\n" ); document.write( "
\n" );
