You can solve this with a proportion:
\n" ); document.write( " $\"+8+%2F+48+=+12+%2F+x+\"$
\n" ); document.write( " $\"+1%2F6+=+12%2Fx+\"$
\n" ); document.write( "Multiply both sides by $\"+6x+\"$
\n" ); document.write( " $\"+x+=+72+\"$
\n" ); document.write( "It will take her 72 minutes to run 12 mi
\n" ); document.write( " \n" ); document.write( "
