Question

if ava's heart beat 747,533 times, how much time elapsed? give your answer in days, hours, and minutes

Answer 1

This question is almost impossible to answer completely. You would have to take into account her resting heart rate, how long and how many times she’s done physical activity, and any mental or health conditions she may have.

However, I’m guessing you’re learning the average resting heart rate and using that for this equation. What you wanna do first is divide 747,533 by the average resting heart rate: 60 - 100 bpm. We’ll use 60.

747,533 / 60 = 12,458.88

Then, you need to convert that to. Days, hours, and minutes.

12,458.88 minutes = 8 days, 15 hours, and 38.88 minutes

Answer 2

Normally a heart beats around 60 to 75 times in a minute. For the calculation of above problem we are assuming that Ava’s heart beats 65 times in one minute.

Therefore, 191.67 hours elapsed if the heart beats 65 times per minute.  

Given:

$\rm Total\: number\: of \:heart\: beats = 747533$

We have to calculate the time elapsed in:

·         Minutes

·         Hours

·         Days

I.   Calculation of time elapsed in minute

$\begin{aligned} \rm Time\:elapsed\:in\:minutes &= \dfrac{\rm Total \:number \:of \:heart \:beats}{\rm Number\:of\:heartbeats\:per\:minute} \\\\&= \dfrac{747,533}{65} \\\\ &= 11500.5 \: \rm minutes \end$

II.  Calculation of time elapsed in hours

We know that 1 hour comprises of 60 minutes,

$\begin{aligned} Time\: elapsed \:in\: hours &= \dfrac{Time\: elapsed\: in\: minutes}{Number\:of\:minutes\:per\:hour} \\&= \dfrac{11500.5}{60} \\\\&= 191.67\: \rm hours\end$

III.  Calculation of time elapsed in days

We know that there are 24 hours in one day.

$\begin{aligned} \rm Time \:elapsed \:in \:days&= \dfrac{\rm Time\: elapsed\: in \:hours}{\rm Number\:of\:hours\:in\:a\:day} \\\\&= \dfrac{191.67}{24} \\\\&= 8\: \rm days \end$

Therefore, 8 days, 191.67 hours or 11500.5 minutes elapsed if the heart beats 65 times per minute.
