Question

restate the following fact as indicated. approximately 102.4 million passengers passed through a certain airport in 2019. because of the coronavirus pandemic, only 42.1 million passengers passed through the same airport in 2020. express these quantities in passengers per hour. there were passengers per hour passing through the airport in 2019 (round to the nearest whole number as needed )

Explanation:

Step1: Convert 2019 passengers to per - hour

First, know that there are 365 days in a non - leap year and 24 hours in a day. So the total number of hours in a year is $365\times24 = 8760$ hours. In 2019, there were 102.4 million passengers. 1 million = 1000000, so 102.4 million = $102.4\times1000000=102400000$ passengers. To find the number of passengers per hour, divide the total number of passengers by the total number of hours in a year.
$ \text{Passengers per hour in 2019}=\frac{102400000}{8760}$

Step2: Calculate the result

$\frac{102400000}{8760}\approx11689.5$
Rounding to the nearest whole number, we get 11690.

Answer:

11690
