Which physical entities equal "distance times time"? Are there useful physical quantities with dimensions of distance-time?
The background for this question is a differential equation which I try to make sense of:

 A: According to Wikipedia, the integral of position with respect to time is called the "Absement" which is a portmanteau of "absence" and "displacement." It seems the quantity is useful for measuring the net/average displacement, as you would divide this integral by the total time interval. It would also be useful for systems in which accumulated distance is dependent on a displacement and the length of a time of a given displacement. Examples include systems which expel power as a function of displacement, i.e. any kind of valve opening.

A: Distance is rate of change of position. Now let's play around with physics formulas:
Acceleration is velocity over time, or distance over time over time, d/t/t. Multiply by time, and you get:
Velocity is distance over time, or distance over time, d/t. Multiply by time, and you get:
Displacement is distance, or position over time, d. Multiply by time, and you get:
Position is distance into time, or position, dt. Multiply by time...
Please give credit if this turns out to be an amazing physics insight.
