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.
Total number of seconds = 1,900 songs * 3.5 minutes/song * 60 seconds/minute
= 133,000 seconds.
We can express this answer in scientific notation as 1.33 × 10^5 seconds.
Therefore, the correct answer is "1.33×10^5 seconds".
To find the total number of seconds the playlist will play, we need to multiply the number of songs by the average song length.
Number of songs = 1,900
Average song length = 3.5 minutes = 3.5 * 60 seconds = 210 seconds
Total time in seconds = Number of songs * Average song length
Total time in seconds = 1,900 * 210 = 399,000 seconds
Expressed in scientific notation, the total number of seconds the playlist will play is 3.99 × 10^5 seconds.
To find the total number of seconds the playlist will play, we need to multiply the number of songs by their average time in minutes and then convert it to seconds.
Step 1: Multiply the number of songs by their average time in minutes
1900 songs × 3.5 minutes/song = 6650 minutes
Step 2: Convert the minutes to seconds
6650 minutes × 60 seconds/minute = 399,000 seconds
So, the total number of seconds the playlist will play is 399,000 seconds.
To express this answer in scientific notation, we need to move the decimal point so that there is one non-zero digit to the left of it.
399,000 in scientific notation is 3.99 × 10^5 seconds.
Therefore, the correct answer is:
3.99 × 10^5 seconds.
