\displaystyle z=\frac{\lambda_o-\lambda_e}{\lambda_e} = \frac{480nm - 660nm}{660nm} = -0.2727

The relativistic doppler equation is:
\displaystyle 1+z=\sqrt{\frac{1+v/c}{1-v/c}}\Rightarrow v=\frac{(z+1)^2-1}{(z+1)^2+1}c=-.3081c

Where the minus sign means that the objects are moving towards eachother.
