Equivalent in time?

[audsnends]

What would be the equivalent ratio of time (minutes) to bits for sound & videos files?

Separately, would wav files and video files have different ratios? If so, a video with sound would it double the ratio?

Hope the way in which if stated my question makes sense.

Thanks for any input.

wouldn't it vary depending on the size/quality of the video and the quality of the audio?
