Answer: The Ferris wheel can hold 576 People in 4 hours
Step-by-step explanation: To find how many people the Ferris wheel can hold in 4 hours, we first want to know how many people the Ferris wheel can hold per minute and per hour.
To find how many people can go on the Ferris wheel per minute, simply divide 60 by 25.
60/25 = about 2.4 people per minute.
There are 60 minutes in a hour, so multiply 2.4 by 60.
2.4 x 60 = 144 People per hour.
We want to know how many people the Ferris wheel can hold in 4 hours. So multiply 144 by 4.
144 x 4 = 576 People that the Ferris wheel can hold in 4 hours.
