Answer:
The roller coaster takes 18 passengers per minute.
Explanation:
A roller coaster can take 162 passengers in 9 minutes. The roller coaster operates at a constant rate.
We have the total passengers T = 162 and the time required t = 9 minutes. We need to calculate the rate of passengers per minute R.
We can find the R dividing the total passengers T by time required t.
R = T/t
R = (162 passengers)/ (9 minutes)
R = 18 Passengers/minute.
Finally, we can conclude that the roller coaster takes around 18 passengers pe minute if it operates at a constant rate.
