Final answer:
Using the provided information, in two years Kelly will be 11 years old, which will be 1/3 of his mother's age. Therefore, Kelly's mother will be 33 years old in two years. Currently, she is 31 years old, but this answer does not match the provided options. There seems to be a discrepancy in the question or the options given.
Step-by-step explanation:
The question is asking to determine Kelly's mother's age based on the information given that in two years, Kelly will be 1/3 of his mother's age. Since Kelly is currently 9 years old, in two years, he will be 11 years old. Hence, at that time, Kelly will be 1/3 of his mother's age. We can set up an equation to solve for the mother's age at that future time:
Let M represent the mother's age in two years.
Kelly's age in two years = 1/3 of mother's age
11 = 1/3 * M
Solving for M, we multiply both sides by 3:
3 * 11 = M
33 = M
Therefore, in two years, the mother will be 33 years old. Since this age is two years from now, we must subtract 2 to find her current age:
33 - 2 = 31
Thus, Kelly's mother is currently 31 years old, but this is not one of the given options, which suggests there may have been a misunderstanding in the question.
