Question

1) A ferris wheel can accommodate 40 people in the 20 minutes. How many people could ride the ferris wheel in 3 hours? What was that rate per hour?

Answer 1

3 hours = 3 x 60 = 180 min, then

40 people ---> 20 min

x ----------------> 180 min

`\begin{gathered} x*20=40*180 \\ 20x=7200 \\ (20x)/(20)=(7200)/(20) \\ x=360 \end{gathered}`

answer 1: 360 people in 3 hours

`(360)/(3)=120`

answer 2: 120 people per hour
