Jim’s music library on his phone holds 1,900 songs. The songs have an average time of 3.5 minutes. Use the scientific notation to find the total number of seconds the playlist will play. Express the answer to the exact decimal place
To find the total number of seconds the playlist will play, we need to multiply the number of songs by the average time per song in minutes and then convert it to seconds.
Number of songs: 1,900
Average time per song: 3.5 minutes
Total time in minutes = 1,900 * 3.5 = 6650 minutes
To convert minutes to seconds, we multiply by 60:
Total time in seconds = 6650 * 60 = 399,000 seconds
Expressed in scientific notation, this is 3.99 x 10^5 seconds.
