A man is x years old and his son is y years old.what is their average age?

Answer 1

To find the average age of the man and his son, you add their ages together and then divide by the number of people.

Given:
- The man's age is \( x \) years.
- The son's age is \( y \) years.

The formula for the average age \( A \) is:

\[ A = \frac{x + y}{2} \]

So, the average age of the man and his son is \(\frac{x + y}{2}\) years.
