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 songs
Average time of each song: 3.5 minutes = 3.5 * 60 = 210 seconds
So, the total number of seconds the playlist will play is:
1,900 songs * 210 seconds/song = 399,000 seconds
Expressed in scientific notation, this is 3.99 × 10^5 seconds.
