SUMMARY
The equation v = qEt/m represents the drift speed of charge carriers in a conductor, where v is the drift speed, q is the charge of the particle, E is the electric field strength, and m is the mass of the particle. The discussion clarifies that while qEt/m gives the final velocity of the particle, the average drift speed is indeed approximated as qEt/(2m) due to the time between collisions. This approximation is valid in introductory physics, where the effects of small values are often simplified for ease of understanding.
