 <translate> Question: Arabella is a dance student learning three new steps this session. Her instructor has her spend thirty minutes on learning the first step. The second step she masters in half the time. The third step is more complex, so it takes her as long as both the other steps to learn. How many minutes did she spend learning the three steps? Think carefully first, then make a decision: <yor> Ìbéèrè: Ọmọ iléèwé tó ń kọ́ ijó ni Arabella, ó ń kọ́ àwọn ìgbésẹ̀ tuntun mẹ́ta nínú ìdánilẹ́kọ̀ọ́ yìí.
