# Break time

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

Result

p =  20.635 %

#### Solution:

$a = 10+20+10+10+5+10 = 65 \ min \ \\ b = 7 \cdot \ 45 = 315 \ min \ \\ \ \\ p = 100 \cdot \ \dfrac{ a }{ b } = 100 \cdot \ \dfrac{ 65 }{ 315 } = \dfrac{ 1300 }{ 63 } \doteq 20.6349 = 20.635 \%$
