What is the distance between each convenience outlet?

What do mean?

I mean I have no idea what receptacle or outlet you are talking about. Are you talking about electrical outlets, and if so, under what conditions do you need to know the distance between any two of them? Is this a homework question? It just doesn't make sense out of context. If English isn't your first language, use Google translator.
