Final answer:
The average weight of the 60 people on the roller coaster when their total weight is 12,000 pounds is calculated to be 200 pounds per person.
Step-by-step explanation:
To find the average weight of the 60 people riding the coaster when their total weight is 12,000 pounds, we use the formula for average:
Average weight = Total weight ÷ Number of people
Plugging in the numbers given:
Average weight = 12,000 pounds ÷ 60 people = 200 pounds per person
Thus, the average weight of each person on the roller coaster is 200 pounds.
