# Audiobook Speed Calculator

Calculate the audiobook length with the given playback speed.

## How to use this calculator?

To calculate the audiobook speed in this calculator:

Based on this information, the calculator should automatically calculate the total playing time of the audiobook for a given speed (e.g. 1.25).

- Enter the total duration of the audiobook.
- Enter the playback speed of your choice (e.g. 1.25, 2, or 0.5).

Based on this information, the calculator should automatically calculate the total playing time of the audiobook for a given speed (e.g. 1.25).

## Math formula

**Total time in seconds**= [(Hours * 3600) + (Minutes * 60) + Seconds] / Playback Speed

**Example:** How much time will it take to listen the 4-hour audiobook at 1.5 speed?

4 hours is equal to 3600 * 4 = 14400 seconds, so:

**Total time in seconds**= 14400 / 1.5

**Total time in seconds** = 9600

To calculate the total time in minutes, divide it by 60:

**Total time in minutes **= 9600 / 60 = 160 minutes

**Answer: **Listening to the 4-hour audiobook at 1.5 speed should take 160 minutes (2 hours and 40 minutes).
