create a proportion like this:
\n" ); document.write( "{{(1/3)/1 = (3/2) / x}}}
\n" ); document.write( "cross multiply to get
\n" ); document.write( "\"%281%2F3%29x+=+%283%2F2%29\"
\n" ); document.write( "multiply by 3 to get
\n" ); document.write( "\"x+=+9%2F2\"
\n" ); document.write( "So, we have 4.5 miles
\n" ); document.write( "
