Answer: The ferris wheel could accomodate 900 people in 6 hours. The rate per hour was 150 people.
Explanation:
To start off we can find the number of people by deciding how many time slots of 30 minutes are in 6 hours. Since 30 minutes is half an hour we just do 2 times 6 which would give us 12. Since 75 people can fit in 30 minutes then we do 12 times 75 for the whole 6 hours which comes out to 900.
Once we have the number of people in 6 hours then we can find the hourly rate. To do this we just take the number of people (900) in the whole time (6 hours) and divide 6 from 900 which would give us the hourly rate of 150.
