code: public static double longitudeDistance(int meters, double latitude) {
          return (meters * 360) / (2 * Math.PI * EQUATORIAL_RADIUS * Math.cos(Math.toRadians(latitude)));
      }
docs: Calculates the amount of degrees of longitude for a given distance in meters.
  
  @param meters   distance in meters
  @param latitude the latitude at which the calculation should be performed
  @return longitude degrees
