Answer:

I think its B

Explanation:

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

[tex]\text{Percentage} (\%) = \dfrac {\rm Value}{\rm Total \;value} \times 100[/tex]

Substituting values we get,

[tex]\begin{aligned} \% &= \dfrac{7.2}{24} \times 100\\\\\% &= \dfrac{720}{24}\\\\&= 30\%\end{aligned}[/tex]

Therefore, 30% of the time is spent sleeping.
