Question

Yolanda collects some data and finds that on average they sleep about 7. 2 hours per day. About what percent of the day do they spend asleep? (A day is 24 hours).

Answer 1

30% of the day they spend asleep.

Sleep is a process of the body that is related to the resting period of the body so that it cannot get fatigued. It is necessary to complete the average sleep cycle to stay healthy.

How to calculate sleep percentage?

Given,

• Sleep per day = 7.2 hours
• One day = 24 hours

$\text{Percentage} (\%) = \dfrac {\rm Value}{\rm Total \;value} \times 100$

Substituting values we get,

$\begin{aligned} \% &= \dfrac{7.2}{24} \times 100\\\\\% &= \dfrac{720}{24}\\\\&= 30\%\end{aligned}$

Therefore, 30% of the time is spent sleeping.
