Answer-

Kai spends 8 hours 20 minutes in school.

Solution-

Let us assume, Kai spends x minutes in school.

Kai calculates that he spends 15% of a school day in science class and that is 75 minutes, i.e

[tex]\Rightarrow x\times \dfrac{15}{100}=75[/tex]

[tex]\Rightarrow x=75\times \dfrac{100}{15}[/tex]

[tex]\Rightarrow x=\dfrac{7500}{15}[/tex]

[tex]\Rightarrow x=500\ \text{minutes}[/tex]

[tex]\Rightarrow x=\dfrac{500}{60}\ \text{hours}[/tex]

[tex]\Rightarrow x=\dfrac{25}{3}\ \text{hours}[/tex]

[tex]\Rightarrow x=8\dfrac{1}{3}\ \text{hours}[/tex]

Therefore, Kai spends 8 hours 20 minutes in school.
