BPM and Pitch

Weird question:
Let's say a song is in the key of E and its bpm is 120.
How many bpms would I have to slow it down on tape so it would be pitched down to D?
Or rather, if i record the song in D on my tape machine what should be the bpm so that when I speed it up to 120 it would be in the key of E?
Is there a formula?

No, I'm not drunk...
I was just listening to The Beatles Strawbery fields forever where the matched two different takes in different keys (and presumably in different tempos) and wondered what the maths behind it are.

I'm guessing they did it by ear back then.

Varispeed on tape machines typically (?) gives you +/- 12% or so, which is enough to go a couple of semitones up or down (and a tad more).
