Final answer:
The question seems to confuse two separate events: the sinking of the Titanic and the torpedoing of the RMS Lusitania. The Titanic hit an iceberg at approximately 11:40 p.m. ship's time on April 14, 1912, while the Lusitania was torpedoed on May 7, 1915.
Step-by-step explanation:
The question seems to be mistaken in its reference, as it confuses the event of the Titanic sinking with the RMS Lusitania being torpedoed. The RMS Titanic struck an iceberg on April 14, 1912, at around 11:40 p.m. ship's time. However, the question provided information about the RMS Lusitania, which was a completely different ship and tragic event. The Lusitania was torpedoed by a German U-boat on May 7, 1915, which led to it sinking in about 18 minutes and resulted in the loss of over one thousand lives. It's important to separate these two historical events and ensure accurate historical information is being conveyed. There is no mention of an iceberg in the context of the Lusitania's sinking, as it was sunk due to hostile military action during World War I.
