It takes .6 s to fill a bottle and move to the next. There are 3600 seconds in an hour. (You are looking at an aweful lot of bottles filled!)

Circle area = pi (r^2) = 3.14 * 2.5 * 2.5
Multiply that product by $3.

Your average is right.

I cannot read your mixed fraction, but if it is 7 3/4, you are right.

5/16 = .3125 > .313

I hope this helps. Thanks for asking.
