Should take only a few seconds to reset the computer in theory. I have found this to be the case in my '99 Mystique & Contours. For my cars, I only remove fuses 4 & 11 from the box under the hood next to the battery. This resets the comuter without losing the station programming in my radio. Fuse numbers may be different in a '96. Check the FAQs at contour.org, or fordcontour.org to confirm which fuses for your car.

how far do i drive my mercury la sable ls to reset emmission control computer
As soon as a battery cable is removed ( negative first ) the computer programming is disrupted . The vehicle will need to relearn its idle , the preset radio stations will need to be reset etc.
If you mean for fuel mix etc comp will reset and relearn after a long enough battery disconnect. As long as engine trans combo matches computer you are fine. If you did a swap, you don't reset it, you get an ECU that matches your combo
50 miles or more

About 5 minutes.
The 1996 Mystique has OBDII (On Board Diagnostics Level 2) and requires a command from a "code reader" or OBDII monitor. It can also be shut off by disconnecting the battery for a long enough period of time, apparently - but I have an Auto XRay unit, so I just use that. If the cause is not repaired, the CEL WILL come back on.
To be completely ready it takes about 30-45 minutes of driving for the computer to complete all tests and to allow smog testing.
