HOW LONG DOES IT TAKE ...?

If we are talking about time, we use the phrase “How long does it take…?”

When we are wondering about the time needed to travel (from place A) to place B, we can ask “How long does it take to get (from A) to B?”:

How long does it take to get from the library to the museum? —It’s about a ten-minute walk.
How long does it take to get to the airport?—About twenty minutes.

We can also use “How long does it take…?” if we are asking about doing something:

How long does it take to bake a cake?
How long does it take to build a house?

The questions can be personalized, as well:  How long does it take you to do something?

How long will it take Tom to clean his room?
It took me forever to finish that project.
