It's for my adult education course and there's no teacher, so I have to research everything online. Well, I'm ok at rearranging equations, but I couldn't find this particular one online or an example of it. Maybe some tips or pointers would be helpful. I have to solve for Ti V = Df -Di/ Tf-Ti So I got to this step V(Tf-Ti) = Df-Di and from there I got to VTf-VTi = Df-Di I have no idea where to go from here; any help would be greatly appreciated.

Requires brackets:
V = Df-Di/ (Tf-Ti)

Make sure you understand why...
