A small insect crawls in the direction of electron drift

A small insect crawls in the direction of electron drift along copper wire that carries a current of 2.56A. It travels with drift speed of the electron in the wire of uniform cross- section area 1 mm² . Number of free elections for copper = 8 x 1022 /cc and resistivity of copper = 1.6 × 10-Nm . How much time would the insect take to crawl 1.0 cm if it crawls at the drift speed of the electons in the wire?
