More Titanic homework

So, Amaia's researching the Titanic and spent this evening making tickets for all the different classes. When she looked up the third-class tickets she was more than impressed that you could get to the USA for just a fiver, especially given she has more than a fiver in her piggy bank.

Then she came out with the sweet but daft statement: If only I had a time machine, I'd go back to 1912 with my fiver and buy a ticket for the Titanic. It's such good value!

I can see a wee flaw with that plan!
