A band's first song is 4 minutes, 12 seconds long and has 462 beats. The band wants to have a second song that is 3 minutes, 54
seconds long with the same beats per minute as the first song. How many beats should there be in the second song?
1 answer:
Answer:
429 beats
Step-by-step 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
Set up a direct proportion using equivalent fractions:
x234=462/252
←beats/←seconds
x=234×462/252
x=429 beats
