### Question:
WGS84Util { public static double getLongitudeDelta(double latitude, double distance) { return Math.toDegrees(distance / getLatitutesCircleRadius(latitude)) % 360; }  static double shortestDistanceBetween(Point a, Point b); static double getLongitudeDelta(double latitude, double distance); static double getLatitudeDelta(double distance); static double normalizeLongitude(double longitude); static double normalizeLatitude(double latitude); static final String EPSG_4326; }### Answer:
@Test public void shouldGetLongitudeDelta() throws FactoryException { assertThat(getLongitudeDelta(toRadians(0), 2 * PI * EARTH_MEAN_RADIUS), closeTo(0, ERROR_DELTA)); assertThat(getLongitudeDelta(toRadians(0), PI * EARTH_MEAN_RADIUS), closeTo(180, ERROR_DELTA)); }
