I wrote the sentence-
キャンパスからEMXバスに乗れば、ユージンバスターミナルまで10ぷんぐらいかかります。
However, I was told by my teacher that かかる has a negative connotation and should not be used when explaining an amount of time that is convenient or quick and that I should use something else? As far as I researched, かかる was used in most examples I could find in the textbook or elsewhere. Is this statement about it being negative accurate? and If so would I just say 時間があります or is there another verb I should use instead?
