Answer:
There would be 429 total beats in the second song. (i hope this helps)
Explanation:
The number of beats is proportional to the time of the song. Convert the time to seconds to avoid recurring decimals.
4 minutes 12 seconds = 4×60+12= 252 seconds
3 minutes 54 seconds = 4×60−6=234 seconds
X/234 =462/252
X= 234 x 462
252
X= 429
