3.99 times 10 cubed seconds
B
0.399×106 seconds
0.399 times 10 superscript 6 baseline seconds
C
3.99×105 seconds
3.99 times 10 superscript 5 baseline seconds
D
3.99×104 seconds
To find the total number of seconds the playlist will play, we need to multiply the number of songs by the average time of each song.
Number of songs = 1,900
Average time per song = 3.5 minutes = 3.5 * 60 = 210 seconds
Total time = Number of songs * Average time per song
Total time = 1,900 * 210 = 399,000 seconds
In scientific notation, the answer is 3.99 × 10^5 seconds.
Therefore, the correct option is C) 3.99×10^5 seconds.
