How many miles off shore did the Titanic sink?

Answer 1

The Titanic sent out a distress call at 12:15am. At about 12:25am, Carpathia contacted Titanic and advised her that she was only 58 miles (93 kilometres) away.

The Carpathia turned around and sped towards Titanic's last known position. At full speed the Carpathia could just manage 20 mph (17 knots). This would have been around 01:00am.

Steaming at 17 knots, Carpathia would have covered the distance in about 2 hours and 54 minutes. Assuming she also had to manoeuvre around ice flows, and get up to full speed, this would agree with the arrival time of about 4:00am at the scene of the sinking.

Carpathia was 58 miles from the Titanic at the time of the message, not when the Titanic sank.

The Titanic sank at 2:20am - just under two hours after Carpathia received the message. So Carpathia would have been steaming at full power for 1 hour and 20 minutes before the Titanic sank

So the Carpathia would have been about 30 -> 32 miles away when the Titanic sank.

Answer 2

Titanic sank about 400 miles from Newfoundland.
