The value of Hubble's constant $H_{0}$ is found to be less than one for non-flat model and is equal to 1.5 for flat model which are of the physical interest. Some physical and geometric properties of the models are also discussed.16 pages, no figure. Submitted in Fizika BGeneral Relativity and Quantum Cosmologytext
