The de-Broglie wavelength lambda

If the wavelength of the electron is numerically equal to the distance travelled by it in one second, then

de-Broglie wavelength lambda is

how fast is an electron moving if it has a wavelength equal to the distance travelled in one second ?

de-Broglie proposed the dual nature of electron and put forward his wave concept. The wave length of electron in an orbit was given by lambda =h/(mv) The de-Broglie.s wavelength (lambda) of the electron subjected to an accelerating potential of V volts is given by
