do nothing #1 can count 5 more ceiling dots per minute than do nothing #2. If they work together for 30 minutes straight, they can count a combined total of 3,450 dots. How many dots can do nothing #2 count per minute?

Answer 1

Let's assume that "do nothing #2" can count x ceiling dots per minute.
Therefore, "do nothing #1" can count (x+5) ceiling dots per minute.

Working together for 30 minutes, the combined total of dots they can count is (30*(x+(x+5))) = 3450.
Simplifying the equation, we get: 30(2x+5) = 3450
Dividing both sides by 30, we get: 2x + 5 = 115
Subtracting 5 from both sides, we get: 2x = 110
Dividing both sides by 2, we get: x = <<55=55>>55.

Therefore, "do nothing #2" can count 55 ceiling dots per minute. Answer: \boxed{55}.
