A new superhero movie has its first showing and there are 155 people in line to see it. If the ratio of kids to adults waiting to see this movie is 3:2, how many adults are I. Line?

The ratio of kids to adults waiting to see the movie is 3:2, which means out of every 5 people in line, 3 are kids and 2 are adults.

Since there are 155 people in line, we can create a proportion to find the number of adults:

3 kids + 2 adults = 5 people

2 adults = 5 people - 3 kids

2 adults = 2 people

So, for every 5 people in line, there are 2 adults.

To find the number of adults in line, we divide the total number of people by 5 and then multiply by 2:

Number of adults = (155 people / 5) * 2 = 31 * 2 = <<(155/5)*2=62>>62 adults.

There are 62 adults in line to see the superhero movie. Answer: \boxed{62}.
