Question

Ava's heart rate is 65 beats per minute. If this is her average heart rate, how many times will her heart beat in 10 years.

Answer 1

there are 60 minutes in 1 hr, so in 1 hour, her heart beats 65(60)

24 hours in 1 day, so it beats in 1 day 24(65 * 60)

365 days in 1 year, so it beats in 1 year, 365(24 * 65 * 60)

how much will it be in 10 years then? 10(365 * 24 * 65 * 60).

Answer 2

Ava's heart will beat for 341640000 beats in 10 years.

Explanation:

Heart rate of Ava is = 65 beats per minute

We have to calculate the heart beat in 10 years.

Since Ava's heart beats in 1 minute = 65 times

Heart beat in 1 hour = 65 × 60

= 3900 beats

Heart beats in 24 hours or one day = 3900 × 24

= 93600 beats

Heart beats in 365 days or 1 year = 93600 × 365

= 34164000 beats

Heart beats in 10 years = 34164000×10

= 341640000 beats

Therefore, Ava's heart will beat for 341640000 beats in 10 years.
