* Longitude: Longitude lines run from the North Pole to the South Pole. They are measured in degrees east or west of the Prime Meridian (0 degrees). So, it's impossible to have a location that's both 175 degrees north and 51 degrees south.

* Latitude: Latitude lines run horizontally around the Earth, parallel to the equator. They are measured in degrees north or south of the equator.

Therefore, there is no place on Earth that can be both 51 degrees south and 175 degrees north.
