Please help me with this electricity and magnitude problem?

If a metal wire carries a current of 75.0 mA,


how long does it take for 6.40 x 10^20 electrons


to pass a given cross-sectional area anywhere


along the wire? The magnitude of the charge


on an electron is 1.6 x 10^-19 C. Answer in


units of s.
