To find out how old Brian’s brother will be when Brian turns 11, let’s first establish their current ages. Right now, Brian is 8 years old, and since his brother is twice his age, we can determine his brother’s current age as follows:
- Brian’s age: 8 years
- Brother’s age: 8 years x 2 = 16 years
Now, let’s calculate how many years it will take for Brian to turn 11:
- Years until Brian turns 11: 11 years – 8 years = 3 years
In 3 years, both Brian and his brother will age 3 additional years:
- Brian’s future age: 8 years + 3 years = 11 years
- Brother’s future age: 16 years + 3 years = 19 years
Therefore, when Brian turns 11, his brother will be 19 years old.
