□b. 1 day
□×d. 365 days / 1 yr
express the 105.3 million passengers that passed through the airport in 2019 in scientific notation.
105.3 million = 1.053×10^8
(type your answer in scientific notation, using the appropriate symbol from the math palette for any multiplication.)
use the chain of conversions to find the number of passengers per day in 2019.
(1.053×10^8 passengers / 1 yr)×(1 yr / 365 days)×(1 day / 24 hr)=(12,021 passengers / 1 hr)
(round to the nearest whole number as needed.)
thus, there were approximately 12,021 passengers per hour passing through the airport in 2019.

Explanation:

Step1: Convert 2019 passengers to standard form

105.3 million = 105300000 = 1.053×10^8

Step2: Calculate passengers per day in 2019

Number of passengers per day = $\frac{1.053×10^{8}}{365}\approx288504$ (rounded to the nearest whole number)

Step3: Convert 2020 passengers to standard form

44.8 million = 44800000 = 4.48×10^7

Step4: Calculate passengers per day in 2020

Number of passengers per day = $\frac{4.48×10^{7}}{365}\approx122740$ (rounded to the nearest whole number)

Answer:

In 2019, there were approximately 288504 passengers per day. In 2020, there were approximately 122740 passengers per day.
