Final answer:
To find the number of minutes you should expect to wait if there are 120 people in line for the swings, you can set up a proportion using the given information and solve for x.
Step-by-step explanation:
To find the number of minutes you should expect to wait if there are 120 people in line for the swings, we can set up a proportion using the given information:
(6 minutes)/(48 people) = x minutes / (120 people)
To solve for x, we can cross-multiply:
6 * 120 = 48 * x
720 = 48x
Dividing both sides by 48, we get:
x = 15 minutes
Therefore, you can expect to wait 15 minutes to ride the swings with 120 people in line.
