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

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

If wavelength is equal to the distance travelled by the electron in one second then

If wavelength is equal to the distance travelled by the electron in one second then

If wavelength is equal to the distance travelled by the electron in one second , then :

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