Consider an expanding sphere of instantaneous radius R whose total mass remains constant

Consider an expanding sphere of instantaneous radius R whose total mass remains constant. The expansion is such that the instantaneous density $\rho$ remains uniform throughout the volume. The rate of fractional change in density $\frac {1} {\rho }\left ( {\frac {d\rho } {dt}} \right )$ is constant. The velocity v of any point on the surface of the expanding sphere is proportional to?
