As a counterpart to best approximation in normed linear spaces,the best coapproximation was introduced by Franchetti and Furi.In this paper,we shall consider the relation between coproximinality M in X and LP(S,M) in LP(S,X).Finally we give some results in cochebyshev subspaces and additional subspaces.
