Answer:
18 times.
Explanation:
The ferris wheel will have to take 48 people repeatedly until all have gone with the last group of people being 48 or less.
Given that there are 823 people with tickets to ride the ferris wheel
Number of time to run the wheel = 823/48
= 17 5/48
It means that the ferris wheel will take 48 people 17 times and 5 people once. Hence it will be run 18 times to give everyone a ride.
