Please answer the following question by reasoning step-by-step.
At 30, Anika is 4/3 the age of Maddie. What would be their average age in 15 years?

50
If Anika is 30 now, in 15 years, she'll be 30 + 15 = 45 years old.

At 30, Anika is 4 / 3 the age of Maddie, meaning Maddie is 4 / 3 * 30 = 40 years.

In 15 years, Maddie will be 40 + 15 = 55 years old.

Their total age in 15 years will be 55 + 45 = 100.

Their average age in 15 years will be 100 / 2 = 50.

.

The final answer: 50
