To find the total number of seconds the playlist will play, we need to multiply the number of songs by the average time of a song.
Number of songs: 1,900
Average time of a song: 3.5 minutes
Total time: 1,900 songs * 3.5 minutes/song
Converting minutes to seconds: 3.5 minutes * 60 seconds/minute
Total time: 1,900 songs * 3.5 minutes/song * 60 seconds/minute
Simplifying the expression: 1,900 * 3.5 * 60 seconds
Using a calculator, we get the result as 399,000 seconds.
Expressed in scientific notation, this is 3.99 x 10^5 seconds.
Therefore, the answer is a) 3.99 x 10^5 seconds.
