Last year there were 3100000 visitors to a national park and, on average, each visitor spends 22 hours in the park on average how many vistors were in the park at any particular time last year

7785

Explanation:

Through some simple calculations, we can figure out how many visitors were in the park at any particular time last year.

The year has 365 days, and each one of these days has 24 hours. Therefore, there are 8760 hours in a year (365*24=8760).

Each visitor that came to the park spent an average of 22 hours, and there were 3100000 visitors. Therefore, 3100000*22=68200000.

If we were to divide the number of hours with visitors by the number of hours in total, we would obtain the average number of visitors that were in the park at any particular time last year:

68200000/8760=7785.39, or 7785 visitors on average.
