The key here is that we cannot use fast (or slow, for that matter) for rate--we don't say a fast or slow rate, do we? we say high or low rate

or, can we say when we say rate--as fast as or faster than becomes redundant..I mean when I say care runs at 30 miles/hour..I am trying to say how fast it runs ...so "as fast as" is redundant when we already have "rate of increase"

Pls refer thread

hmm. i'm not even sure how to label "twice" formally as a part of speech in this sort of instance, but "X is twice Y", where X and Y are both nouns, is extremely common usage.
in this case, it seems as though "twice" is acting as an adjective, and yes, my dictionary says it's an adverb. but "X is twice Y" is definitely considered correct.

i'm not sure whether this is an official problem, but, even if it isn't, there are similar usages in official problems i've seen: "twice the figure for...", etc.

you may just want to memorize this as a particular allowed construction, without trying too hard to stick labels on it. remember that it doesn't matter whether you can label words correctly (as parts of speech, etc.); all that matters is that you can tell which constructions are right and which are wrong.

@Ron,

I don't know the source, i have picked this question from another forum
please let me know the question number if you have seen this usage in official guide. (I know, its a pain to look back for a specific question, but still if you remember or come across something similar, do let me know :-))

I was reffering to the question128 OG11 here.

Thanks,

I thought, "X is twice Y" is fine, as twice is acting as an adverb modifying the linking verb "is" just as q128 (OG11) does!

Did i miss something ?

you may be right. but the principal point i'm trying to make is this:
the only thing that matters is that "x is twice y" is fine.
the gmat is not going to ask you to classify words according to parts of speech, so, in the final analysis, the particular part of speech here - whether adjective, adverb, or pink flamingo - is irrelevant.

don't spend an inordinate amount of time labeling things with linguistic terms, especially in esoteric cases such as this one. (in other words, labeling things may be helpful if you're trying to learn GENERAL RULES, but this case is most assuredly not a general rule.) instead, just learn what works and what doesn't, because that's all you're going to need to know.

@ROn: Its an OG paper set 48 Q no 17

its more than twice...

see the close answers:

(B) twice as fast as it was in
(C) twice what it was in

Can you please explain: as fast as vs what?

Uses of twice is always like an adverb in gmat dictionary though...

two reasons that (c) is better:

* (b) is more wordy. this reason is easier to notice, but less reliable (since wordiness/concision is absolutely the LAST criterion you should ever use to decide a problem).

* in formal writing, a RATE can't be FAST. also, as long as we're on the topic, a SPEED can't be FAST, either.
you can have a rate that's twice another rate (NOT "twice as fast as" another rate), or you can have an increase that's twice as fast as another increase.
as another poster has already pointed out above, it's redundant, and therefore undesirable, to include both "fast" and "rate".
