Based on this answer, I would like to know why it's really odd to say:
Fixing the problem took me two hours more than it took me to find the problem.
I know we can (or should) use ellipses, I intentionally wrote the sentence in the full version without any deletion.
The Question: I want to know what's wrong with that dummy subject it? What makes the sentence ungrammatical? I am not asking whether my sentence is wrong or right because as the cited answer says it's not right.
- It took me two hours to find the problem.
It took me four hours to fix the problem.
- Hence, Fixing the problem took me two hours more than it took me to find the problem.
About the cited post:
"B. She was a good student, finishing in half the time it took the others to finish."
"Sentence B also sounds really odd. You should rephrase it like: ...finishing in half the time the others took to finish."
