To calculate the Playlist Length (PL):
\[ PL = SL \cdot S \]
Where:
Playlist Length is the total duration of all the songs in a playlist. It is calculated by multiplying the average length of a song by the number of songs in the playlist. This calculation helps in determining how long a playlist will play, which can be useful for planning events, workouts, or any activity that requires a specific amount of music.
Let's assume the following values:
Using the formula:
\[ PL = 4 \cdot 15 = 60 \text{ minutes} \]
The playlist length is 60 minutes.
