Answer 1

To find the total number of seconds the playlist will play, we need to multiply the number of songs (1,900) by the average time of each song (3.5 minutes) and convert it to seconds.

First, we can convert 3.5 minutes to seconds:

3.5 minutes * 60 seconds/minute = 210 seconds

Then, we can multiply the number of songs by the average time in seconds:

1,900 songs * 210 seconds/song = 399,000 seconds

Expressing this in scientific notation, we get:

3.99 × 10^5 seconds
