# Break time

Calculate how many percent of school time is spent on breaks. Calculate data for the whole week.

Correct result:

p =  20.635 %

#### Solution:

$a=10+20+10+10+5+10=65 \ \text{min} \ \\ b=7 \cdot \ 45=315 \ \text{min} \ \\ \ \\ p=100 \cdot \ \dfrac{ a }{ b }=100 \cdot \ \dfrac{ 65 }{ 315 }=\dfrac{ 1300 }{ 63 }=20.635 \%$
