In 3e, ideally, but if not, anywhere (2e, 4e, etc)...is there a rule for how far you fall in a round?
d = AT^2

High-Altitude Falls: Some encounters take place very high above the ground. In such an encounter, it is possible for a creature to spend more than one round falling to the ground. As a rule of thumb, a creature falls up to 500 feet during its first turn of falling. If it is still falling at the start of its turn, it can take actions on that turn as normal, then falls up to 500 feet at the end of the turn. If none of those actions expressly halts a fall, the creature falls up to 500 feet at the end of the turn. This sequence continues until the creature lands.
A nonflyer (or flyer falling through the air) freefalls rather than stalls. A creature in freefall drops 500 feet the first round and 1,000 feet each round thereafter. While in freefall, a creature can attempt a single action each round. It must make a Dexterity or Strength check (creature's choice, DC 15) to avoid dropping any item it tries to use. Spellcasting is possible, but doing so requires a Concentration check (DC 15 + spell level) and if the spell has a material component, the creature must first check to see if it drops the component.
