6. Ana would need to extend her trip by two days. She would need at
least 8 days total to participate in all activities. I found this by
dividing the total number of activities by 3 to get 7.333… Since she
will only be there 6 days and would need more than 7 days to
complete all activities, she would need to extend her trip by two
days.
