Question

A student is curious as to how many times his heart beats in on day. If his heart beasts 65 times each minute, how many times will his heart beast in 24 hrs.

Answer 1

a.) His heart beasts 65 times each minute.

Let's determine how many times will his heart beast in 24 hrs.

`\text{ }\frac{65\text{ beats}}{1\text{ \lparen minute\rparen}}\text{ x }\frac{60\text{ \lparen minutes\rparen }}{1\text{ \lparen hour\rparen}}\text{ x }\frac{24\text{ \lparen hour\rparen}}{1\text{ day}}\text{ }`
`\text{ = }\frac{\text{65 x 60 x 24 beats}}{\text{ 1 x 1 x 1 day}}`
`\text{ = 93, 600 beats/day}`

Therefore, his hear beats 93,600 beats/day
