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
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 = 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).
