How it works

Questions

How long is a 10-hour audiobook at 1.5x speed?

6 hours 40 minutes. At 2x it takes 5 hours, and at 1.25x it takes 8 hours.

How do I calculate listening time at a different speed?

Divide the length by the speed. A 12-hour audiobook at 1.5x takes 12 ÷ 1.5 = 8 hours.

How long is a 1-hour video at 2x speed?

30 minutes. At 1.5x it takes 40 minutes, and at 1.25x it takes 48 minutes.

How fast can I play YouTube videos?

The YouTube speed menu goes from 0.25x to 2x. Audiobook and podcast apps set their own limits, so check the speed menu in yours.

Is there a faster way to get one answer from hours of content?

If you want what one person said about your question, ask a mentor built from their videos and podcasts. You get the answer with links to the exact moments, without listening to the rest.
