Answer:
The answer is 1/2 or 3/6. In time form 30 minutes.
Explanation:
Kim eats 1/3 of an apple in 1/6, so by the time they finish eating the apple, it'll be 3/3 (of them eating the apple), which would lead to 3/6 or 1/2 (the time they finished the apple). So in half of an hour they'll finish eating the apple. Hope this helps.
