You can put this solution on YOUR website!
Let +t+ = her time in minutes to type and spell checking 1 page
+6%2F22+=+1%2Ft+
Multiply both sides by +22t+
+6t+=+22+
+t+=+3.667+
Now let +t%5B2%5D+ = her time for +27+ pages
+1%2F3.667+=+27%2Ft%5B2%5D+
+t%5B2%5D+=+3.667%2A27+
+t%5B2%5D+=+99+
It will take her 99 min or 1 hour and 39 min
