Hi this is my first post. This subject may had been discused, but I do not know how to search it. I want to make a linear motion. I need the algorithm or functions to these problems:

- Move object from x,y to x2,y2 with linear motion, the function should return the time it took to complete the translation (with given velocity), and another function to calcute the velocity giving the time argument

- Would it be too hard to implement in a 3D environment?

Sorry for bad English / Double post
Be gentle on me
