Question

A healthy human heart beats about 1,533,000 times a year. A sparrow's heart beats about 241,776,000 times in a year. About how many times faster does the sparrow's heart beat compared to the human heart?

Answer 1

About 158 times

Explanation:

Represent the rate of human heart with H and sparrow's heart with S

`H = 1,533,000\ times`

`S = 241,776,000\ times`

Required

Determine how many times faster is S than H

To do this, we simply divide S by H i.e.

`Number = (S)/(H)`

`Number = (241,776,000)/(1,533,000)`

`Number = 157.714285714`

`Number = 158` --- approximated

Hence, the sparrow's heart beats about 158 times faster than the human hearts
