The Brazilian carnival takes place once a year only.
It depends on the year. But it is ALWAYS 40 days before Easter. (40 days before is the 'quarta feira de cinzas' so the real carnival begin the Friday before that, and it ends 40 days before Easter)
To get ready for what?
Because they have not been taught to get ready quickly or efficiently
One day.
100,000,000 that means 100 million (this seems like a gross overestimate. half of the population of Brazil goes to carnival in Rio? I have actually gone. It is crowded but not that much. Maybe this estimate is recounting people for each day. Officially Carnival is only 4 days but in practice there are events spread over 2 weeks.)
Anywhere inside (and in some meaning... outside too) the county something about carnival may happen, but basically out in the streets as well as in clubs, in podiums in squares and so on - no matter, either in big cities or in villages too (depending on each group of folks with their customs [tradition of amusing or not] or without such).
Cookies typically take about 10-15 minutes to cool before they are ready to be eaten.
The overall distance is about 54 miles. The estimate time it will take is about 52 minutes.
