Problema Solution
Ana is composing a piece of music as background sound for a video her friends are making. The music is 1 minute and 45 seconds long, and it has 210 beats in it. Find the beats per minute rate of the music?
Answer provided by our tutors
1 min 45 sec = 60 + 45 sec = 105 sec
the rate is 210 beats/105 sec = 2 beats/sec = 2*60 beats/min = 120 beats/min
