Set up a proportional equation:
\n" ); document.write( "12feet/40 minutes = 6 feet/x minutes [Cross-multiply]
\n" ); document.write( "12x=(40)(6)
\n" ); document.write( "12x=240
\n" ); document.write( "12x/12=240/12
\n" ); document.write( "x=20 minutes [Final answer]
\n" ); document.write( ".
\n" ); document.write( "Check by pluggin x=20 back into the original equation.
\n" ); document.write( "
\n" );
