It looks like there might have been a mistake in your question. It reads: "If the average age of 6 people is 15 people." The term "people" should be replaced with a unit of time, like years, for ages. You probably meant to ask something like:
"If the average age of 6 people is 15 years, what is their combined age?"
The average age is calculated by dividing the total combined age of all individuals by the number of individuals.
Given:
- Average age = 15 years
- Number of people = 6
To find the combined age of all individuals:
\[ \text{Combined age} = \text{Average age} \times \text{Number of people} \]
\[ \text{Combined age} = 15 \, \text{years} \times 6 \, \text{people} \]
\[ \text{Combined age} = 90 \, \text{years} \]
So, the combined age of the 6 people is 90 years.
