There is no definitive answer to this question as it depends on a number of factors, including the type of fruit, the growing conditions and the storage conditions. However, some fruits generally take longer to ripen than others, such as avocados, bananas and pears.
Avocados are a type of fruit that takes a long time to ripen. They are usually picked when they are still hard and green and then left to ripen at room temperature. This can take anywhere from a few days to a couple of weeks. Once ripe, avocados should be eaten within a day or two as they will start to go off quickly.
Bananas also take a while to ripen properly. Unlike avocados though, bananas should not be left out at room temperature as this will cause them to over-ripen and become mushy. Instead, they should be stored in a cool place until they reach the desired level of ripeness (usually when they have started to turn yellow). Once ripe, bananas can be kept for another day or two before they start to go off.
Pears are another type of fruit that takes longer than most others to reach peak ripeness. Like bananas, pears should not be left out at room temperature as this will cause themto over-ripen and become mushy; instead store them in a cool place until readyto eat (usually when they have turned from greento yellow). Ripe pears canbe kept for up tp three days before startingto go off
