Solved for
bitrate
Worked out from Bitrate, duration and file size relation: size = bitrate x duration, converting bits to bytes by a factor of 8 and 1 other source.

How this is worked out

2 steps
  1. Bitrate = 1 MB x 8 / 1 s = 8 Mbit/s
  2. That is 0.001 GB decimal, or 0.0009 GiB as an operating system reports it.
