How long did the royal mail ship titanic sink

I think there may be some confusion here!

The RMS Titanic was not a Royal Mail ship. It was a British passenger liner that sank in the North Atlantic Ocean in the early morning of April 15, 1912, after colliding with an iceberg during her maiden voyage from Southampton to New York City.

The Titanic was owned by the White Star Line, a shipping company that operated a fleet of passenger liners. The ship was not operated by the Royal Mail, which is a postal service that delivers mail and packages.

The Titanic sank approximately 2 hours and 40 minutes after hitting the iceberg, at around 2:20 am on April 15, 1912. The ship went down in the freezing waters of the North Atlantic, resulting in the loss of over 1,500 lives.
