For anyone confused, どちら can mean both Which one? and Which way? in English.

Think of it as asking for a general direction (Which way…?). This works for both physical and intangible options (Which thing…?). It is essentially a polite way to ask Which <anything>…?.

When used as Which one…?, it's generally for when the are only two options.

E.g.
リンゴと バナナと どちらがすきですか。(Out of apples and bananas, which do you like?).
きたは どちらですか。(Which way is north?).
スミスさんは どちらですか。(Which one is Mr. Smith?)

Sometimes, in a formal setting, "dochira" is used instead of "doko". Both mean where under this particular situation.

銀行の出口はどちらですか？

What is the difference between 'doko' and 'dochira'?

I always learnt どちらas which one? As in this sentence would mean, which one is the bank's exit? Being said as you point to two doors.

This makes me imagine a situation where you are not inside the bank, but want to figure out where the cash trucks exit so you could rob them. If you simply wanted to know how to enter the bank you'd ask for the entrance.

"Bank's exit" is OK in English, but not "the exit of the bank." Clearest would be "Where is the exit from the bank?" or, "Where is the exit out of the bank?"

Same here, どちらですか literally means "which one" so in this sentence, it shoukd be "which one in the bank exit"

I confess to some confusion on this answer. I assumed that the topic was directions, and that this would mean "which is the exit for the bank". In other words, which exit from the main road. But it seems we are talking about how to get out of the bank?

So is it okay if I just use doko always since it's just much more clearer to me?

I like that I was able to abuse Duolingo's tile options and put 'Where's the bank exit?' and it still marked it right. Take that Duo!

"which is the bank exit" could be correct dependant on context.

"Where is the exit to the bank" is apparently wrong. Thanks Duo!

I agree with Slinky656524 - "where is the exit to the bank?" should be accepted. The word "to" is not used in the directional sense here. Rather, it is used as a possessive: it means the same as "where is the bank's exit"

Wrong answer because missed "the". Are we testing japanese or English?

Would "Which way to the bank's exit?" also be acceptable? Duo marked wrong, I know there's no "to" in this sentence but that's how I'd normally ask in english, without specifying "the bank". "Which way to the exit" / "Which way is the exit"?

Salty that using "where" is still wrong. Flagged.

"Where is the exit to the bank?!", you ask the scared onlookers as you make your (uninformed) escape.

It's always this... You seek for an entrance to the hospital, but for an exit to the bank...

銀行の出口はどちらですか

Can we please include the Kanji answer??

It should accept "where is the exit from the bank?" because you'd never say "of the bank"

Where's the bank's entrance =/= wrong
