To solve this you need to divided 0.33 in 2. Because 2 meters. So, 0.165 per minute. But the question is per second, so we need to divided 0.165 by 60. In doing that, you get 0.00275 meters per second. For the 2nd question, we do 0.165 multiplied by 3 to get the answer of 0.495 meters in 3 minutes. I hope my answer helps!
