There is a misunderstanding in your friend's statement. The longitude coordinates typically range from 0° to 180° E and 0° to 180° W, with the Prime Meridian at 0°. However, the latitude coordinates range from 0° at the equator to 90° N at the North Pole and 90° S at the South Pole.
Therefore, when your friend mentions a town at latitude 60°E, it's not possible because the latitude values do not extend beyond 90°. The latitude coordinates are used to determine the north-south position on Earth, while the longitude coordinates determine the east-west position.
