Question

If your heart beats 22 times in 15 seconds, what is your heart rate in bpm's? ​

Answer 1

88 bpm

Step-by-step explanation:

A minute is equal to 60 seconds, so we can setup an equation with
`(22)/(15) = (x)/(60)` with beats/second. We can cross multiply to get 1320 = 15x. Now we can divide 1320 by 15 to get 88. Our final answer would be 88 bpm. (You can also just multiply 22 by 4 because 15 is 1/4 of 60)
