You have to keep your vertical speed high enough to maintain your air speed high enough to avoid stalling. I assume the modern planes are able to control all of this (vertical and air speed) with the automation to get the optimum glide profile and distance. The pilots just have to figure out where they can land within glide range, usually choices on the FMC, but if over the ocean, may have to ditch. I used to practice this in FSX flight sim, it's actually very difficult to time the glide just right so that you end up at the threshold of the runway at the right speed and vertical rate. This assumes either the APU is running or the RAT deployed for electric and hydraulic power and fully operational controls, otherwise you are going down.

Air Transat Flight 236 successfully glided 75 miles and they have to perform circles to lower the altitude based on this i can say easily 100 Miles

What if your cruising altitude was at 38,000ft or 40,000? How many miles would that be?

How long can a modern jet glide with both engines out from cruise altitude?
