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

Last year, being a non-leap year, there were 365 days

So, number of hours in last year = 365 x 24 = 8760

Total number of man-hours spent in the National park = 3100000 x 22, i. e. number of visitors x hours spent by each visitor

We can find out average number of visitors in the park at any time during that hour as = (3100000 x 22) / 8760 = 7785.388 visitors
