Answer:
Your answer should be 3 roller coasters
Step-by-step example:
A roller coaster fit 11 people, and there are 34 people in the line.
Therefore you will have to multiply that by 3 which gives you 33, now there's you and the person in front of you, since you count 34 people in front of you, not including yourself. There's 3 more roller coaster rides to go before you get on.
