1.	In winters, a school opens at 10 a.m. and closes at 3.30 p.m. If the lunch interval is of 30 minutes, find the ratio of lunch interval to total lime of the class periods.
Answer» Timing of a school (10 a.m. to 3.30 p.m) = 5 hours 30 minutes Timing for lunch interval = 30 minutes Total time of the class periods = 5 hours 30 minutes – 30 minutes = 5 hours = 60 x 5 = 300 minutes Ratio of lunch interval to total time of the class period = 30 minutes : 300 minutes = 1 : 10

In winters, a school opens at 10 a.m. and closes at 3.30 p.m. If the lunch interval is of 30 minutes, find the ratio of lunch interval to total lime of the class periods.

Answer»

Timing of a school (10 a.m. to 3.30 p.m) = 5 hours 30 minutes

Timing for lunch interval = 30 minutes

Total time of the class periods = 5 hours 30 minutes – 30 minutes

= 5 hours = 60 x 5 = 300 minutes

Ratio of lunch interval to total time of the class period = 30 minutes : 300 minutes = 1 : 10
