I only have the time equation and I get 0.69 seconds... but how do i get the quantity?

Answer 1

Hz is a measure cycles or events per second. Multiply by 60 to find minutes. 1.45 beats / 1 second x 60 seconds / 1 minutes. Seconds cancel out leaving 87 beats per minute.

Answer 2

Hz stands for Hertz, base unit is cycle/s or in simpler terms 1 (One) hertz means one per second.

So 1.45 * 60 (60 seconds make a minute)= 87 beats per minute.

Answer 3

Hertz is a unit of measure that says how many cycles the event happens in a second.

1.45Hz means, during one second, it happens 1.45 times. If you want a minute, multiply this by 60. (60 seconds in a minute)

Answer 4

1.45 Hz means 1.45 beats in a minute
so there a re 1.45 * 60 beats in a minute, which is = to 87 beats in minute

Answer 5

1.45x60=87bpm Hz=beats per second
60 seconds in a minute
