An electroplating cell is used to coat a metal ornament with a thin layer of silver.
During the process, a steady current of 125 mA is maintained through the cell.
A total charge of 135 C passes through the electrolyte.
Calculate the duration of this electroplating process, giving your answer in minutes.
