Final answer:
Gina and her family waited for 3 hours in line at Superhero Mountain Amusement Park.
Step-by-step explanation:
The question is asking how long Gina and her family waited in line at Superhero Mountain Amusement Park. The given graph shows the wait times in hours. The x-axis represents the number of people in line and the y-axis represents the wait time in hours. To determine how long Gina and her family waited, we need to find the value on the y-axis corresponding to the x-value that represents the number of people in line.
From the graph, we can see that when there are 2 people in line, the wait time is 3 hours. So, Gina and her family waited for 3 hours in line.
