Unity 2D make object which is more in depth to move slower then other objects

Hello, how can i make object move slower whichone is on Z -50 as object which is on Z = 0. for example when i want to make panoramatic background maded from 3 pieces, then first one moving constantly with player, second one move 33% slowly as first one and 3rd one move 33% slower as second one (or 66% as first one). I think i can do it easily with c# script, but its possible to do it easily or with integrated method? Thanks

easily i mean parallax effect. my first idea is to make background as main object and then mid object must move for about 5 velocity more and foreground for 10 more as background, i think this can work. but what i mean in Q, if its possible to do it directly in editor
