    Answer:

    45 (minutes) or 3/4 of an hour

    Step-by-step explanation:

    On the first week she played 2 3/4 hours which translates to 2 hrs and 45 minutes (165 min), and this week she played for 3 2/4 hours which is 3 hours and 30 minutes (210 minutes)

    Then just do 210 minus 165, and you’ll get 45 minutes, which can also be said as 3/4 of an hour.
