Problem $18\mathrm{.}016-$ Time taken for a conduction electron to move along a copper wire

A current of $10\mathrm{.}0$ A is carried by a copper wire of diameter $1\mathrm{.}40$ mm $.$ If the density of the conduction electrons is $8\mathrm{.}47{10}^{28}{m}^{-3},$ how long does it take for a conduction electron to move $2\mathrm{.}80$ m along the wire?
