Answer 1

70% of study time - 91 minutes

10% of study time - 13 minutes

100% of the study time - 130 minutes

Explanation:

To find the time for 10% of the study time, divide 70% = 91 by 7

10% = 13, so 10% of her study time was 13 minutes.

100% of her study time is 10% * 10 or 13 * 10 = 130 minutes.
