You can put this solution on YOUR website!
Let $\"+y+\"$ = number of pages read
\n" ); document.write( "Let $\"+x+\"$ = minutes to read $\"+y+\"$ pages
\n" ); document.write( "ЧЧЧЧЧЧЧЧ-
\n" ); document.write( "For direct proportion I can say:
\n" ); document.write( " $\"+y+=+k%2Ax+\"$ where $\"+k+\"$ is a constant
\n" ); document.write( "ЧЧЧЧЧЧЧЧ-
\n" ); document.write( "If $\"+y+=+20+\"$ , then $\"+x+=+45+\"$
\n" ); document.write( " $\"+20+=+k%2A45+\"$
\n" ); document.write( " $\"+k+=+4%2F9+\"$
\n" ); document.write( "ЧЧЧЧЧЧЧ
\n" ); document.write( "If $\"+x+=+18+\"$ then:
\n" ); document.write( " $\"+y+=+k%2A18+\"$
\n" ); document.write( " $\"+y+=+%284%2F9%29%2A18+\"$
\n" ); document.write( " $\"+y+=+8+\"$
\n" ); document.write( "ЧЧЧЧЧЧ-
\n" ); document.write( "You can read 8 pages in 18 min
\n" ); document.write( " \n" ); document.write( "

\n" );
