# How long does the walking take? (Is this structure possible?)

We can make a question sentence like below:

1. How long does it take to walk?
2. How long does it take you to walk?

How long + does + NOUN FORM OF A VERB AS SUBJECT + take?

(How long does the walking take?)

And can we give an answer like:

The walking takes half an hour.

If we can't make a structure like I wrote, Is it valid for only "How long does it take?" sentence pattern?

(Because, I've seen a sentence like "How long does the alcohol stay in your body?" on internet.)

• How long does the walk take? Sure. Where walk is a noun. Walking can also be a gerund noun but then you would say: Walking [to work] takes half an hour. Commented Aug 22, 2021 at 14:59
• But Ronald Sole said that you can't use the gerund form below the page. Is it because we need to specify the sentence? Is "Walking to work takes half an hour" sentence correct? Commented Aug 22, 2021 at 15:11
• No, he says not to use "the walking". How long does walking take? [gerund noun] NO THE. :) Or "Walking to work takes 1/2 hr. Again, no "the" Commented Aug 22, 2021 at 19:06

The two numbered sentences you quoted would sound strange as they stand: you need to specify which particular walk you are talking about, and use a noun rather than a gerund, for example

How long does it take you to walk to work?"

You could re-organize this as:

How long does your walk to work take?

If the listener already knows which walk you are talking about, you could reduce this to:

How long does the walk take?
How long does it take?

The walk takes half an hour.
It takes half an hour.

You can use a gerund walking in place of the noun walk, but you would use it differently.

How long does walking to work take?

If the listener knows what walk you are talking about, you would normally go directly to the fully ellipsized version:

How long does it take?

You would only keep the gerund and omit the other details if you needed to be specific about the mode of transport, for example to compare with cycling.

How long does walking take? = compared to cycling

Likewise, in a reply, you would be very unlikely to repeat the gerund, unless you need to be specific, for example, to contrast it with other modes of transport:

It takes half an hour
Walking takes half an hour: cycling takes ten minutes.

As Ronald Sole mentioned, you should not use a definite article with walking in this sentence.

Generally speaking, you don't use articles with gerunds. They are normally considered uncountable, so you never use a/an with a gerund. There are, however, exceptions but they are not well documented. There is some information about this in section 133 of the Oxford Guide to English Grammar (John Eastwood, 1994)

There are situations where we do use a definite article with a gerund, for example when talking about specific parts of something:

I found the swimming in the triathlon the hardest part.
I usually enjoy the walking part of my journey to work.

We use a definite article when a gerund is followed by of:

The playing of games is prohibited

We use a definite article when a gerund is considered countable, for example the set phrase

The comings and goings

When a gerund is used in a compound noun, the countable-ness is determined by the final word, so you cannot say

a hill walking

But you can say

a hill walking holiday
a walking holiday

• But NOT how long does the walking take. or The walking takes.... They are not idiomatic constructions. Commented Aug 22, 2021 at 14:13
