A bands first song is 4 minutes, 12 long and has 462 beats the band wants to have a second wants to have a second song that is 3 minutes, 54 seconds long with the same beats per minute as the first song. There would be (blank) total beats in the second song.

4 minutes and 12 seconds is the same as 4.2 minutes

12/60 = 0.2

4 + 0.2 = 4.2

462 beats in 4.2 minutes means 110 beats per minute

462 / 4.2 = 110

y = 110x

3 minutes and 54 seconds is the same as

54/60 = 0.9

3 + 0.9 = 3.9

y = 110 (3.9)

y = 429 beats

First we need to find the beats per minute of the first song. 12 seconds needs to be converted to 12/60 minute, which is 2/10 minutes: 0.2 minutes.

The 4.2 minute song had 462 beats.

462/4.2 = 110 beats per minute.

The second song has 3 min 54/60 min = 3.9 min.

Therefore 3.9 x 110 = 429 total beats.
