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.
