Give the step-by-step reasoning process and then the final answer. A dog barks 30 times per minute. If 2 dogs bark 30 times per minute, how many times will they have barked after 10 minutes?
There are 2 dogs and they each bark 30 times per minute so together they bark 2 * 30 = 60 times per minute. 2 dogs bark a combined total of 60 times per minutes, after 10 minutes they will have barked 60 * 10 = 600 times.
The final answer: 600.
