Te-form beginner question


> いもうとは東京に行っています。

How can I discover the meaning of this sentence? I'm studying the te-form and
I'm a little bit confused. The correct translation will be:

> My little sister is in Tokyo (she´s already there)

or

> My little sister is going to Tokyo (progressive action) ?

Or I see by the context? This verb form is SO damnnn cruel to learn ;___;




I would simply say いもうとは東京にいます for "My little sister is in Tokyo."

いもうとは東京に行っています has the connotation that she is _away_ in Tokyo, hence she is
not here.

I would say いもうとは東京に行くところです (or いもうとは東京に向け移動中です if you prefer a more formal
style) for "My little sister is going to Tokyo."

*** added *** I think @Choko's choice 妹は東京に向かっています works as well.
