Answer: 624
To determine the number of vehicles that would pass through the checkpoint in a 24-hour period, we can use the information given in the problem.
We are told that an average of 26 vehicles per hour passed through the checkpoint over a three-day period.
To find the number of vehicles that would pass through the checkpoint in a 24-hour period, we can multiply the average number of vehicles per hour by the number of hours in a day (24).
So, the calculation would be: 26 vehicles/hour * 24 hours/day = 624 vehicles/day.
Therefore, the correct answer is 624
