Did pretty good on the first question Phil. Now for #2 This Navy guy (a submariner-are they still Navy if they go under water instead of on top? At any rate, gets my claustrophobia up just thinking about it.) This navy guy has a 5 gallon bucket of rocks. Each rock weighs 6 ounces except for one on the bottom of the bucket that has a 2 ounce chip off it. The bucket of rocks weighs 55 1/2 pounds. Now this Navy guy is better than a Marine. He can kill two birds with one stone (Chipping Sparrows specifically). Now this is not the birds in the bush story, that is something altogether different. Once this Navy guy gets in position to start throwing at the chipping sparrows, how many birds will he kill with the bucket of rocks knowing he can kill 2 of the poor little devils with each throw? He has to be careful 'cause there will be catfish guys out there picking up those 6 ounce stones for weights. This question has a Spocklike logical answer which I can't figure out 'cause I hate math. You could give me any answer and I would say you are right, but I want you to try or other members can kibitz with you . This is a timed test Phil. Not something a mechanic likes to hear I know. I'll give you less than a week to figure it out. Pretend you are making up a clients bill and it will be easy. Obviously since you are dealing with me I am looking for a different answer and we will see how anybody does. Later, John. P.S. or B.S. depending on how you look at it, these are polished granite stones the Navy guy stole from a Japanese garden before the Marines could get there and get them themselves.
