As a result of increased productivity, in the last day before the deadline, they only had to clean 30 acres. The group of farmers had to clean 6 acres of wheat. How many additional acres per day did the new machinery help them clean? Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags.<|im_end|>
