document.write( "\n" );
document.write( "There are 60 minutes in an hour.\r<BR>\n" );
document.write( "\n" );
document.write( "Now we have to use a unit multiplier (you will see below):\r<BR>\n" );
document.write( "\n" );
document.write( "25 miles/hour X 1 hour/60 minutes = 25 miles x hour / 1 hour x 60 minutes.\r<BR>\n" );
