Answer:
The total number of people who can ride the ferris wheel is 440.
Explanation:
There are four sets of 15 in an hour. (60 minutes/15 minutes= 4)
If 55 people can ride the ferris wheel in 15 minutes then 220 people can ride the ferris wheel in one hour. (55 people X 4 = 220). If 220 people can ride in an hour then you simply double that and you get 440 people can ride in two hours.
