What is the speed of a 796eV electron?

2. Relevant equations

E = hc/lambda

E = hv

3. The attempt at a solution

I'm not sure how to get a value for meters... I know if I take h (plank's constant) and divide the electron, I will get 4.14E-15 ev*s / 796 eV = 5.20E-18 seconds, but that is just a time, i don't know how to get the distance for that time...
