If 1 inch represents 45 miles, how many inches represent 315 miles?
\n" ); document.write( "Divide 315 by 45.
\n" ); document.write( "315/45 = 7 inches.
\n" ); document.write( ".
\n" ); document.write( "Do it the opposite way for the second part.
\n" ); document.write( "45 miles * 18 inches = 810 miles apart
\n" ); document.write( "
\n" );
