To find the average number of passengers processed over the two days, first, let's calculate the total number of passengers processed each day. On the first day, Officer Ferong processes 16 passengers every 40 minutes. In 4 hours, there are 6 intervals of 40 minutes (since 4 hours equals 240 minutes, and 240 divided by 40 equals 6). Multiplying the number of passengers processed per interval by the number of intervals gives: 16 passengers/interval * 6 intervals = 96 passengers on the first day. On the second day, Officer Ferong processes 18 passengers every 40 minutes. The calculation for the second day will follow the same logic, as it is also a 4-hour period: 6 intervals of 40 minutes mean: 18 passengers/interval * 6 intervals = 108 passengers on the second day. Now, to find the total number of passengers processed over the two days, add the numbers from each day: 96 passengers (first day) + 108 passengers (second day) = 204 passengers total. Finally, to find the average number of passengers processed per day over the two days, divide the total by 2: 204 passengers / 2 days = 102
