Consider the question. Samir just turned half the age Hania was 10 years ago. If in five years Hania will be 45 years old, what will Samir's age be five years from now?
 If the answer is '20'; explain the reasoning:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

If in five years, Hania will be 45 years old, currently she is 45 - 5 = 40 years old. Ten years ago, Hania was 40 - 10 = 30 years old. Samir just turned half the age Hania was 10 years ago, which means she is 30 / 2 = 15 years old. In five years, Samir will be 15 + 5 = 20 years old.
