The Playback Speed Calculator is majorly used for estimating the time saved by watching or listening to content at increased speeds. This can be particularly helpful for speeding through lectures, podcasts, or lengthy videos while retaining valuable information.

Adjusting playback speeds greatly aids users to maximize learning efficiency and entertainment time. Thus, it allows them to control how long they engage with media.

Formula:

$R = \frac{V}{T}$

Symbol	Description
$R$	Adjusted time based on speed
$V$	Original video or audio duration
$T$	Speed multiplier (e.g., 1.5x, 2x)

Solved Calculations:

Example 1:

Step	Calculation
Original Duration (V)	2 hours
Playback Speed (T)	1.5x
Adjusted Time Calculation	$\frac{2}{1.5} = 1.33$ hours
Result	1.33 hours (80 minutes)

Answer: A 2-hour video at 1.5x speed takes 1.33 hours (or 80 minutes) to watch.

Example 2:

Step	Calculation
Original Duration (V)	3 hours
Playback Speed (T)	2x
Adjusted Time Calculation	$\frac{3}{2} = 1.5$ hours
Result	1.5 hours

Answer: A 3-hour video at 2x speed takes 1.5 hours to watch.
