It takes me an hour to go to school

[keannu]

There's many uses of "it" Is the following "it" a false subject or impersonality subject?
By false subject, I mean as in "It is hard to work out everyday" (To work out is the real subject)
By impersonality subject, I mean subjects indicating time, weather, distance, weight, etc not related to persons. In this sense, this "it" can seem time and "to go to school" seems a purpose as an adverbial usage.
This was a question of a middle school reference book, so I got confused. I need your kind answer.

There's no possibility for it in "It takes me an hour to go to school" to be a time indicator as an impersonal subject, right?
Do you have the concepts of impersonal subjects(weather, time, distance, etc) and "false subject" vs "real subject"(when real subject is too long, it's placed at the end)?

No.

It takes me an hour to go to school. = To go to school takes me an hour.
It is hard to work out everyday. = To work out everyday is hard.

Are you asking whether I understand what you mean by "impersonal subject" and "false subject"? Then yes. If you're asking whether these are common terms, then I don't know.
