there are 24 hours in a day, 7 hours in a week, so
there are 7%2A24+=+168 hrs/wk
There are 3600 sec/hr
There are 3600%2A168+=+604800 sec/wk
5%2F60 quarts/sec = 1%2F12 qt/sec
A swimming pool has 4%2A65000+=+260000 qts of water
1%2F12 qt/sec x 604800 sec/wk = 50400 qts/wk
260000 qts/pool divided by 50400 qts/wk = 5.159 wks/pool
