Step-by-step explanation:
According to the U.S. Census Bureau, about 63% of Americans are adults (18 and over). Use the U.S. population estimate of 308 million people to calculate the number of American adults in 2010. Round to the nearest hundred thousand adults
540 people can ride the wild river in 1 hour if all of the rafts are used and each raft is full
<u>Solution:</u>
Given, There are 15 rafts available for people to use on the adventure river ride.
Each raft holds 12 people.
Then, total people capacity over all rafts = 15 x 12 = 180 people.
The park runs this ride 3 times each hour.
We have to find how many people can ride the wild river in 1 hour if all of the rafts are used and each raft is full?
Then, <em>total people count who take ride = number of rides x number of people per ride
</em>
= 3 x 180 = 540
Hence, 540 people can take ride in 1 hour.
Terminating because the decimal ends rather than going on forever which would be repeating
