LaVilla is a village in the Italian Alps. Given its enormous popularity among Swiss, German, Austrian, and Italian skiers, all of its beds are always booked in the winter season, and there are, on average, 1465 skiers in the village. On average, skiers stay in LaVilla for 11 days. How many new skiers are arriving - on average - in LaVilla every day

There are approximately 133 new skiers arriving every day

Step-by-step explanation:

Total number of skiers = 1465

time of stay for skiers = 11 days

How many new skiers are arriving on average = ???

To keep the average number of skiers available at each time constant, the number of skiers coming in and going out are fairly constant, and this is gotten by using the flow rate formula.

flow rate = amount available  ÷ flow time

flow rate = 1465 ÷ 11

flow rate = 133.18

flow rate = 133

∴ There are approximately 133 new skiers arriving every day
