Galina-37 [17]

Answer:

About 158 times

Step-by-step 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.

$Number = \frac{S}{H}$

$Number = \frac{241,776,000}{1,533,000}$

$Number = 157.714285714$

$Number = 158$ --- approximated

<em>Hence, the sparrow's heart beats about 158 times faster than the human hearts</em>
