Let the speed be x
\n" ); document.write( " $\"3%2Fx-9%2Fx=1\"$
\n" ); document.write( "9x-3x=(x)(x)
\n" ); document.write( " $\"6x=x%5E2\"$
\n" ); document.write( " $\"x%5E2-6x=0\"$
\n" ); document.write( "Factor left side:
\n" ); document.write( "x(x-6)=0
\n" ); document.write( "x=0 or x=6
\n" ); document.write( "hence, the jogging speed is 6mph.
