Scale: 1cm = 12 km\r
\n" ); document.write( "\n" ); document.write( "Goal: Convert 15cm to km.\r
\n" ); document.write( "\n" ); document.write( "Using dimensional analysis:\r
\n" ); document.write( "\n" ); document.write( "15 cm (12km / 1 cm) [make sure that cm is on the bottom since this is the given unit]\r
\n" ); document.write( "\n" ); document.write( "15 * 12 = 180\r
\n" ); document.write( "\n" ); document.write( "Hence, 180km.
