# Calley's 80s Music Recording Party Playlist

## How long was the recording?

Calley put together a recording of 80s music to play at her party. She recorded a total of 15 songs. Each song lasted 3 minutes, with a ten-second break between songs.

a) 45 minutes and 10 seconds

b) 30 minutes and 150 seconds

c) 45 minutes and 150 seconds

d) 150 minutes and 45 seconds

## Answer:

The total duration of the recording is made up of 45 minutes from the songs and about 2.33 minutes from the breaks, making the recording about 47.33 minutes long.

To find the length of the total recording, we'll first calculate the duration of the songs and then add the duration of the breaks. Calley recorded a total of 15 songs, and each song lasts 3 minutes, so that makes the total duration of songs as 15 * 3 = 45 minutes.

Now, let's calculate the break time. There's a 10-second break between each song, and since there are 15 songs, there will be 14 breaks (one less than the number of songs). Thus, the total break time is 14 * 10 = 140 seconds. We need to convert these seconds into minutes. As 60 seconds is equivalent to 1 minute, 140 seconds is equivalent to about 2.33 minutes (140 / 60 = 2.33 minutes).

When we add these two durations together, we get the total length of the recording as 45 + 2.33 = 47.33 minutes. So, none of the provided options is correct.
