Answer 1

Answer:

160 minutes or two hours and 40 minutes

Step-by-step explanation:

        First, let's divide 2 hours of total work by the 15 minutes chunks she does.

2 hours = 120 minutes

120 minutes / 15 minutes = 8

        She will have 8 sessions of studying with a break. Now we can calculate the total.

[] 120 minutes of studying

[] 8 * 5 minute break = 40 minutes of break

[] 120 + 40 = 160 minutes
