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 of Each Song: 3.5 minutes
Total time in minutes: 1,900 * 3.5 = 6,650 minutes
Now, we need to convert the total time from minutes to seconds. Since there are 60 seconds in 1 minute, we can multiply the total time in minutes by 60.
Total time in seconds: 6,650 * 60 = 399,000 seconds
Therefore, the answer is 3.99 x 10^5 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 in minutes and then convert it to seconds.
Step 1: Multiply the number of songs by the average time per song.
1,900 songs * 3.5 minutes = 6,650 minutes
Step 2: Convert minutes to seconds.
1 minute = 60 seconds
6,650 minutes * 60 seconds/minute = 399,000 seconds
Step 3: Express the answer in scientific notation.
The answer, 399,000 seconds, can be written in scientific notation as 3.99 × 10^5 seconds.
Therefore, the correct option is:
3.99 × 10^5 seconds
To find the total number of seconds the playlist will play, we can multiply the number of songs by the average time of each song.
Number of songs = 1,900
Average time of each song = 3.5 minutes
To convert minutes to seconds, we multiply by 60:
Total number of seconds = 1,900 songs * 3.5 minutes/song * 60 seconds/minute
Calculating this expression gives us:
Total number of seconds = 399 * 10^6 seconds
So the correct answer in scientific notation is 3.99 × 10^6 seconds.
