A school start at 8 a.m and get over at 1.30 p.m during the school time if there are two breaks of 15 minutes and 30
minutes ,respectively, find the ratio of the break time to the total time the students in the school
Answers
Answer:
first we will calculate the number of minutes from 8:00 am to 1:30 pm and that is 330 minutes than we will subtract the two breaks of 30 and 15 minutes from 330 minutes means subtract 45 from 330 and we get 285 minuter and than divide 285/330 and we will get 19/22 so the answer is 19:22
Ratio of the break time to the total time the students in the school is 9 : 66
Solution:
Given that,
A school start at 8 a.m and get over at 1.30 p.m
Find the total time the students in the school
Total time = 8 am to 1 : 30 pm
Total time = 5 hours 30 minutes
We know that,
1 hour = 60 minutes
5 hours = 5 x 60 = 300 minutes
Therefore,
Total time = 300 minutes + 30 minutes = 330 minutes
Find the ratio of the break time
During the school time if there are two breaks of 15 minutes and 30 minutes respectively
Total break time = 15 minutes + 30 minutes = 45 minutes
Find the ratio of the break time to the total time the students in the school
Ratio = 45 : 330
Reduce to lowest term
Ratio = 9 : 66
Thus ratio of the break time to the total time the students in the school is 9 : 66
