Steve: 20 drinks in 5 minutes => \"20%2F5=4\" drinks per minute\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Sue: 20 drinks in 10 minutes => 2 drinks per minute\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Jack 20 drinks in 15 minutes => 4/3 drinks per minute\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Together they mix 4 + 2 + 4/3 = 12/3 + 6/3 + 4/3 = 22/3 drinks per minute\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"20%2F%2822%2F3%29=60%2F22=30%2F11\" minutes, very roughly a little less than 2 and 3/4 minutes.
