3241004551 [841]

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.
