You might want to run through some tutorials before going on. I'm not trying to be rude but you do have 3 posts and they are all on this particular thread. It is beneficial to do a number of tutorials and get to understand the logic behind game development in Construct 2. Otherwise this will be an everlasting thread of us telling you how to build a paperboy clone.
Remember, this is all math, so without understanding math it might be hard to do what you want. Algebra is the most basic and most used of all in any programming environment (eg: Set movement to Variable+Variable/2). So again, go do the tutorials and you'll understand more about how C2 works, and if you need, there are plenty of algebra tutorials (and more) online in various resources like math.com or watch videos on YouTube.
Good luck!
