document.write( "Question 1006572: My hippo's bathtub takes 6 minutes to fill to the top. On the other hand, it empties somewhat slower: it takes 9 minutes to empty the full tub. One day my hippo was very busy and didn't notice that the stopper wasn't in when he turned the water on. How long did it take to fill the tub this time? How much water was wasted? \n" ); document.write( "

Fill rate both parts open is \"1%2F6-1%2F9\"
\n" ); document.write( "\"%283-2%29%2F18\"
\n" ); document.write( "\"1%2F18\" TUB per MINUTE, which means 18 minutes to fill the tub this way.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "RT=V, and units of volume V is in TUBs. Uniform rate rule for flow rates.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Volume used for filling just from inlet pipe,
\n" ); document.write( "\"%281%2F6%29%2A18=3%2Atubs\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Volume which went out while filling, because drain was open,
\n" ); document.write( "\"%281%2F9%2918=2%2Atubs\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3-2=1%2Atubs\"
\n" ); document.write( "Amount of water lost was 2 tubs-worth.
