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 in minutes and then convert it to seconds.
Number of songs: 1,900
Average time of each song: 3.5 minutes
Total time in minutes: 1,900 songs × 3.5 minutes/song = 6,650 minutes
Now, we need to convert the time in minutes to seconds. Since there are 60 seconds in a minute, we multiply the total time in minutes by 60:
Total time in seconds: 6,650 minutes × 60 seconds/minute = 399,000 seconds
Expressing this in scientific notation:
3.99 × 10^5 seconds
Therefore, the correct answer is 3.99 × 10^5 seconds.
Jim's music library on his phone holds 1,900 songs. The songs have an average time of 3.5 minutes. Use scientific notation to find the total number of seconds the playlist will play. Express the answer to the exact decimal place. (1 point)
