Consider sea level to be zero.
\n" ); document.write( "So the sub is at -450, and the plane is 832.
\n" ); document.write( "To find the distance between 2 points, subtract them. Let d be the distance...
\n" ); document.write( "\"d=832-%28-450%29\"
\n" ); document.write( "\"highlight%28d=1282%29\" meters
