F = Δp/Δt

(Sorry for bad sketch.. hehe)
In the kinetic-molecular theory of gas, the Δp is -2mv (since it's supposed to be elastic collision)
But, why the Δt is 2L/V ??
I think it must be a very small time (since the impact is done in a very very small time)
Why the time is the interval time before the velocity gets back to the initial velocity ?
