Say a sorcerer already knows the mage hand cantrip, and then takes the Telekinetic feat. If they cast mage hand and apply the Metamagic option Distant Spell to it, what would its range be?
(Ignore the fact that, by RAW, the hand disappears if it's ever more than 30 feet from the caster.)
The description of the Metamagic option Distant Spell says:
When you cast a spell that has a range of 5 feet or greater, you can spend 1 sorcery point to double the range of the spell.
The second benefit of the Telekinetic feat says (TCoE, p. 81):
You learn the mage hand cantrip. [...] If you already know this spell, its range increases by 30 feet when you cast it.
Both effects apply "when you cast".
What is the range of the mage hand spell if the Telekinetic sorcerer uses Distant Spell when they cast it?
Is it 90 feet ((2 × 30) + 30)?
Or is it 120 feet (2 × (30 + 30))?
Is there anything RAW about ordering effects with the same trigger, or is it just DM fiat?
