Answer:
Kindly check explanation
Step-by-step explanation:
Based on the infomation given :
Number of frozen fruit per box = 12
The number of people the makes up the committee should be given on other to obtain an exact answer.
To obtain the number of boxes of frozen fruits :
We divide the Number of committee members by the number of frozen fruits per box ; that is
1f number of committee members = x
Number of frozen fruits per box = 12
Number of boxes to order = x / 12
If number of committee members is given, substitute the number for X
Answer: 3.4 h
Explanation:
1) The basis to solve this kind of problems is that the speed of working together is equal to the sum of the individual speeds.
This is: speed of doing the project together = speed of Cody working alone + speed of Kaitlyin working alone.
2) Speed of Cody
Cody can complete the project in 8 hours => 1 project / 8 h
3) Speed of Kaitlyn
Kaitlyn can complete the project in 6 houres => 1 project / 6 h
4) Speed working together:
1 / 8 + 1 / 6 = [6 + 8] / (6*8 = 14 / 48 = 7 / 24
7/24 is the velocity or working together meaning that they can complete 7 projects in 24 hours.
Then, the time to complete the entire project is the inverse: 24 hours / 7 projects ≈ 3.4 hours / project.Meaning 3.4 hours to complete the project.
