Fernanda purchased six audiobooks from Audible to listen to from her audible app. If each audiobook was 30 hours long and she listened to 2 hours of an audiobook each day, calculate the total time it took her to finish the six audiobooks?
To finish an audiobook 30 hours long, listening to 2 hours of each audiobook a day, Fernanda took 30 hours / 2 hours/day =15 days to finish one audiobook.
If she purchased 6 audiobooks, the total number of days she will take to finish all the audiobooks is 6 audiobooks * 15 days/audiobook = 90 days
