In this text. "Hotel Ice is made of 250 tons of ice. It takes 8 weeks to build".
The pronoun "it" substitute "the hotel" or "to build".
Does the last statement mean the same that: "It takes 8 weeks to build it".
Please, explain it.
Can I say "They take 8 hours to get home" or do I have to say "It takes 8 hours for them to get home".
Thanks a lot in advance.
