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

$\begin{gathered} x\times20=40\times180 \\ 20x=7200 \\ \frac{20x}{20}=\frac{7200}{20} \\ x=360 \end{gathered}$

answer 1: 360 people in 3 hours

$\frac{360}{3}=120$

answer 2: 120 people per hour
