Explanation
List Eva’s meditation sessions and breaks:
10:10–10:30 session 1
10:30–10:35 break
10:35–10:55 session 2
10:55–11:00 break
11:00–11:20 session 3
Note that the question asks for the time when she will complete her third session, so do not add a third break!
A quicker way to do this problem would be to add 20(3) + 5(2) to get 70 minutes, and 70 minutes after 10:10 is 11:20.
Hence option A is correct!
