From the dictionary hints ви = you, чули = hear (past tense)/ heard, їі = her. Therefore "Did you hear her" one of two possible solutions. The one that is listed above uses the word "did" to establish the past tense of the sentence the alternative is to use the past tense of the verb itself. This means that actual literal word for word translation "You heard her" is equally correct. It will also help connect the two words based on the tense.
