SUMMARY
The drift speed of electrons in a copper wire is approximately 0.020 mm/s. Given a total wire length of 40 meters, it would take a single electron approximately 69.44 days to drift from the negative terminal of the battery to the positive terminal and back. The relationship between distance, time, and speed is defined by the equation: time = distance/speed, which is crucial for calculating the time taken for electron drift in this scenario.
