How can you make it go a certain distance?

We have to build catapults in school and the teacher wants us to hit targets placed 2-4 meters but to get it to go a certain distance (2.2) How can I do it mathematically (with protectors or measuring length)? What formulas can I use?

- Also the targets will be randomly placed the day i have to shoot it
