To find this out, we begin by performing 2 * 2 = 4 hours spent on day two, double what she spent on day 1. Next, we perform 4 - 1 = 3 hours to determine the amount she studied on the third day. We then add 2 + 4 + 3 = 9 hours spent in total across 3 days. Since there are 60 minutes in an hour, she studied 9 * 60 = 540 minutes in total.
Thus, the answer is 540.
