In winters a school opens at $10$ a.m and closes at $3.30$ p.m. If the lunch intervals is of $30$ mins find the ratio of lunch interval to total time of the class periods

Open in App

Solution

Total Time in the school $= 5 h r 30 m i n = 330 m i n$
Lunch Time $= 30 m i n$
Total Time in the class periods $= 330 - 30 = 300 m i n$

Therefore, the required ratio
$= \frac{30}{300}$
$= \frac{1}{10}$

Hence, the ratio is $1 : 10$ .
