There is no definitive answer to this question as it can vary greatly from person to person. However, some people might consider an average of 100 free times to be around 60-90 minutes per day. This could be used for things like taking a leisurely walk, reading a book, or simply spending time with loved ones. It is important to remember that everyone's definition of an average 100 free time will be different, so it is best to ask others what they consider to be an average 100 free time for them.
