Jim's music library on his phone holds 1,900 songs the song has an average time of 3.5 minutes use scientific notation o 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 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 = Number of songs × Average time of each song
Total time in minutes = 1,900 × 3.5
Total time in minutes = 6,650
Now, we need to convert this total time in minutes to seconds. Since there are 60 seconds in a minute, we can multiply the total time in minutes by 60.
Total time in seconds = Total time in minutes × 60
Total time in seconds = 6,650 × 60
Total time in seconds = 399,000
The total number of seconds the playlist will play in scientific notation is expressed as 3.99 × 10^5 seconds.
