Your last two look right, but let's look at the first two.
First, it's much easier if you have all of you units the same...so turn everything into seconds. We're looking for 2 hours. Since there are 60 sec in a minute and 60 minutes in an hour (times 2 hours), there will be 7200 seconds in 2 hours. It takes .6 seconds to fill one bottle and move the next into place. Therefore, you will divide 7200 by .6 to get your answer. You came up with either 1 or less. If your answer doesn't make sense it can't be right.
For the next question, you need to find the area of the surface of the table.
pi x r squared r=2.5
So, 2.5 x 2.5 x 3.14....take this answer and multiply by 3 to get your answer.
