You can put this solution on YOUR website!
In words:
[ number of pages read ] = [ rate of reading in pages/min ] x [ time spent reading ]
Let +t+ = time spent reading in minutes
+45+=+%28+15%2F10+%29%2At+
+45+=+%28+3%2F2+%29%2At+
+t+=+%28+2%2F3+%29%2A45+
+t+=+30+
It will take her 30 min to read 45 pages
