How many times do the dogs bark together? ** There are 2 dogs and they each bark 30 times per minute so together they bark 2*30 = <<2*30=60>>60 times per minute
How many times will the dogs have barked after 10 minutes? ** 2 dogs bark a combined total of 60 times per minutes, after 10 minutes they will have barked 60*10 = <<60*10=600>>600 times
