Answer 1

To find the average length of a song on Caden's CD, divide the total length of the CD (49 minutes) by the number of songs (8), which equals 6.125 minutes. After rounding to the nearest hundredth, the average length of a song is 6.13 minutes.

Step-by-step explanation:

The question asks us to find the average length of the first song on Caden's CD, knowing that there are eight songs with a total length of 49 minutes. To find the average song length, we divide the total length by the number of songs.

1. Divide 49 minutes by 8 to find the average length of each song.
2. 49 ÷ 8 = 6.125 minutes.
3. Round the result to the nearest hundredth to get the average song length.
4. 6.125 minutes rounded to the nearest hundredth is 6.13 minutes.

The correct answer is A) 6.13 minutes, which represents the unit rate or average length of a song on Caden's CD.
