Hi Kathi, I'm not sure where you are getting "we". If you mean where is the subject, since it is a question and there is no subject in the sentence then it's implied that the listener is the subject. :)
As bonus info, days use their own counting system:
하루: one day 이틀: two days 사흘: three days 나흘: four days 닷새: five days 엿새: six days 이레: seven days 여드레: eight days 아흐레: nine days 열흘: ten days
Am I not understanding some context to this sentence, or is there no verb? 이틀 = two days, 동안 = for, 어디가 = where?
