Question

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 1

Solution:

Timing of a school (10 am to 3.30 pm)

= 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 total time of the class period

= 30 minutes : 300 minutes = 1:10

Answer 2

Answer:

10:1

Step-by-step explanation:

Given-

School opens at 10:00pm and ends at 3:30 pm.

Time for lunch interval = 30 minutes

to find- ratio of lunch interval to total time of the class?

sol-

1 hour = 60 minutes

thwrefore, time for classes = 330 - 30 = 300 minutes

ratio = 300:30 = 10:1

hence, the ratio is 10:1.
