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.

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.

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
