Calculation of the Number of Lifeboats Needed

To determine the number of lifeboats needed, we need to consider the following information:

- There are 44 adults and 352 children on the ship. - Each lifeboat can accommodate either 10 adults or 20 children. - Each lifeboat must have at least two adults.

Let's break down the calculation step by step:

1. Determine the maximum number of adults that can be accommodated in each lifeboat: 10 adults per lifeboat. 2. Determine the maximum number of children that can be accommodated in each lifeboat: 20 children per lifeboat. 3. Calculate the total number of adults that need to be accommodated: 44 adults. 4. Calculate the total number of children that need to be accommodated: 352 children. 5. Determine the number of lifeboats needed to accommodate the adults: Divide the total number of adults by the maximum number of adults per lifeboat. 6. Determine the number of lifeboats needed to accommodate the children: Divide the total number of children by the maximum number of children per lifeboat. 7. Add the number of lifeboats needed for adults and children to get the total number of lifeboats needed.

Let's calculate the number of lifeboats needed:

1. Maximum number of adults per lifeboat: 10 adults. 2. Maximum number of children per lifeboat: 20 children. 3. Total number of adults: 44 adults. 4. Total number of children: 352 children.

Now, let's calculate the number of lifeboats needed for adults and children separately:

- Number of lifeboats needed for adults: 44 adults / 10 adults per lifeboat = 4.4 lifeboats. Since we need to have at least two adults in each lifeboat, we round up to the nearest whole number. Therefore, we need 5 lifeboats to accommodate the adults.

- Number of lifeboats needed for children: 352 children / 20 children per lifeboat = 17.6 lifeboats. Since we need to have at least two adults in each lifeboat, we round up to the nearest whole number. Therefore, we need 18 lifeboats to accommodate the children.

Finally, we add the number of lifeboats needed for adults and children to get the total number of lifeboats needed:

5 lifeboats (for adults) + 18 lifeboats (for children) = 23 lifeboats.

Therefore, to accommodate 44 adults and 352 children, we need a total of 23 lifeboats.

Please note that the calculation assumes that each lifeboat can only accommodate either adults or children, and that there are no other restrictions or considerations mentioned in the question.
