In this question we have the values the number of beats we can write it as n which is equal to 40 beats.
00:09
Then the row n or del n which is equal to 1.
00:14
The time t which is equal to 30 seconds.
00:19
Time is 30 seconds.
00:22
Then next del t change the time that is 0 .5 seconds.
00:28
Again, using these values, we can first find out the number of beats per minute.
00:35
So, k per minute, which is equals to n divided by t, multiplied by 60, because we want to convert it into the minute.
00:47
So on a simplification, it becomes 40 divided by 30, multiplied by 60.
00:52
So this becomes around 80 beats per minute.
01:02
Now for a maximum beats, for number of maximum beats, this becomes n max, which is equals to n plus dellen, that is 40 plus 1.
01:18
So it becomes 41 beats.
01:20
And therefore time max also becomes t minus del t which is equals to 30 minus 0 .5 that is 29 .5 seconds...
