Answer: B
Explanation:
To calculate the number of departing passengers accessing the front-end only once to check in per hour, we follow these steps:
1. Total Departing Passengers in January:
o 465,000 passengers transported throughout January.
2. Duration of Operations in January:
o Operating hours: 07:00 to 23:00, which equals 16 hours per day.
o Total days in January: 31 days.
o Total operating hours in January: 31 days * 16 hours/day = 496 hours.
3. Passengers Per Hour:
o Total passengers: 465,000.
o Total hours of operation: 496 hours.
o Passengers per hour: 465,000 passengers / 496 hours = 937.5 passengers/hour.
4. Passengers Accessing Only Once for Check-In:
o 30% of departing passengers reconnect for a boarding pass, which means 70% access only once.
o Passengers accessing only once: 70% of 937.5 passengers/hour = 0.70 * 937.5 = 656.25 passengers/hour.
Given the available options, the closest correct value is C. 625.00 departing passengers / hour.
