Mia is a student. In her final year, she spent 1/5 of her day watching TV and 1/4 of the time left on studying. How many minutes did she spend studying each day?
Thoughts? Step-by-step reasoning:
If Mia spent 1 / 5 of her day watching TV, her remaining time in a day is 5 / 5 – 1 / 5 = 4 / 5 for other things. So, the time left is 24 * 4 / 5 = 19.2 hours. The time spent studying is 19.2 / 4 = 4.8 hours. In minutes, that is 4.8 * 60 = 288 minutes.
Thus, the answer is 288.
