3.99×104 seconds
3.99 times 10 superscript 4 baseline seconds
3.99×105 seconds
3.99 times 10 superscript 5 baseline seconds
3.99×103 seconds
3.99 times 10 cubed seconds
0.399×106 seconds
To find the total number of seconds the playlist will play, we can multiply the number of songs (1,900) by the average time of each song (3.5 minutes) and then convert the result to seconds.
1,900 songs * 3.5 minutes/song = 6,650 minutes
Next, we need to convert minutes to seconds. Since there are 60 seconds in a minute, we can multiply the number of minutes by 60.
6,650 minutes * 60 seconds/minute = 399,000 seconds
In scientific notation, 399,000 can be written as 3.99 × 10^5.
Therefore, the correct answer is:
3.99 × 10^5 seconds
