Answer
The electrons from metal 1 have a lower speed than the electrons from metal 2.
Work Step by Step
We can write an expression for the maximum kinetic energy of the electrons:
$K_{max} = \frac{h~c}{\lambda} - E_0$
Note that $E_0$ is the work function.
If the work function of metal 1 is greater than the work function of metal 2, the electrons from metal 1 will have a lower kinetic energy then the electrons from metal 2.
It follows that the electrons from metal 1 have a lower speed than the electrons from metal 2.
