Final answer:
To accommodate 72 riders on the Raptor rollercoaster, which takes 18 riders in 8 minutes, it would take 32 minutes, since it is a direct proportion calculation (72 is four times 18, hence 8 minutes multiplied by 4).
Step-by-step explanation:
The question pertains to the calculation of time based on a given rate of riders accommodated by the Raptor rollercoaster at Cedar Point. If the rollercoaster can accommodate 18 riders in 8 minutes, then the rate at which riders are accommodated is 18 riders per 8 minutes. To find out how long it would take to accommodate 72 riders, we apply direct proportion. Since 72 is four times 18, it will take four times the amount of time to accommodate 72 riders. Therefore, the rollercoaster will take 8 minutes × 4, which equals 32 minutes.
