What is the 3-second rule?

It's an "urban legend" that says any food that drops on the floor is "safe" from contamination for three seconds.

The defensive 3 seconds rule was created to complement the new rule of allowing teams to play zone defense.  Previously, in the NBA, teams were not allowed to play any kind of zone defense.  An illegal defense was called if two players on defense double-teamed a player on offense that did not have posession of the basketball.  This rule has been eliminated, because teams can now play 2-3 / 3-2 / box-1/ any kind of zone.  However now, the 3 second defensive violation, which results in an automatic team technical foul, occurs if any player on defense is not guarding/within arms-length reach of any player on offense for 3 seconds, once the ball crosses half court.

there are 60 seconds in a minute so if you have 27 minutes you multiply, 27 x 60 gives you 1620 seconds, divided by 18 seconds, gives your 90  there is a calculator located on your computer go to start, programs, accessories, calculator.... check out the answer for yourself... it's the best way to learn how to do the math

tell him/her to subtract the minutes first.they should end up with 7:55. then have them subtract 3 from 7

at 3 sec r = 3*8 = 24m\n\na = pi*r^2\n\nda/dt = d(pi*r^2)/dt \nda/dt = 2*pi*r*(dr/dt)\nda/dt = 2*pi*24*8\nda/dt = 384*pi\nda/dt = 1206.4 meters^2 per sec

10:15+ (90/4) = 10:37.5, but that doesn't really matter, b/c the next time when the overlapping/little over fifteen minutes later thing works is 3:15, to 3:33 (you could even say 33 seconds as well) and then 3:33 and 33 secs + 4.5 hours =\n\nSally woke up at 8:03 and 33 seconds

Lets say its 3:25 now. \n\n5 minutes ago it was 3:20 which makes (4 times 5 many minutes) past 3.\n\nNow if it is 3:25 now then its 155 minutes to 6\n(35 min 3:25 to 4 + 60 min 4 to 5 + 60 min 5 to 6).

The Rule of Threes is an uncomplicated way to remember the basic priorities of the human organism, and it is a good starting point for an exploration of survival priorities. The Rule of Three's looks like this:\n\nA person can live for:\nThree minutes without air.\nThree hours without shelter.\nThree days without water.\nThree weeks without food.\nThree months without love.\n\nLet's take a quick look at these priorities and try to understand the them a bit better.\n\nAir\nIf you can't breathe, make it so you can. If you can't make it so, die. End of story.\n\nShelter\nI frequently ask new survival students the question, "If you were lost in a blizzard without your gear what would you do?" The answer I hear most (and which confounds me), sounds something like this. "Build a fire and search for wild food." I can see it now: lost in a howling blizzard, the wind whipping the trees to rubble, frost forming on even the memories of warmth, while our hopeful survivor tunnels through snowdrifts in search of "wild edibles." I wonder if my Turkish friend was thinking of food when he laid down beside that boulder. Without proper shelter, he probably died within three hours.\n\nIt seems obvious our survivor must react immediately to the threat posed by the cold blowing storm. Only hours of life remain if the basic shelter needs are not met. Miserable and hungry, cold and scared, but alive if the shelter is properly constructed.\n\nThe wind dies, the snow moves from its horizontal path to one more nearly vertical and then stops altogether. The trees shiver as great blobs of storm-driven snow loosen and fall to earth. A patch of blue as the clouds part. Then the first muted mutterings of the forest are heard as signs of life begin to return. The hunched form of the rule-following survivor shoves aside parts of the hastily erected debris-shelter and he sets forth in quest of the next priority. Water.\n\nWater\nLike the sailor lost at sea with "water, water everywhere and not a drop to drink," our survivor first gobbles a handful of snow to help fill the rapidly developing vacancy in the hungry center. Oops. That won't do, either. It takes energy to turn snow into water. Snow may be only about 20% -30% water by volume yet it takes lots of energy to convert the cold snow into warm water. Where is the energy going to come from? No food to eat, and none in the stomach. There will be no power from the fat battery for some time. (It takes many hours to start receiving energy from our fat reserves. We need to stay alive until those reserves are available to us.) Our friend is still powered by the energy stored in the bones and blood. Water will be necessary to assist the energy extraction processes the body uses when converting fat into energy. Lack of water, the third priority, can stop us from utilizing even our own reserves. With dehydration we discover another interesting relationship between water and our chances for survival.\n\nFor each five percent our body dehydrates (by weight - i.e. a 100 pound body weight reduced to 95 pounds by dehydration), we lose approximately 25% of our ability to do work. Some authorities claim an even a greater loss of power.\n\nRemember, this is in addition to the loss of ability to do work caused by insufficient energy. The ratio of work energy lost versus the percentage of dehydration remains relatively constant until the victim is literally unable to continue to function. The percentages look something like this.\n\nPercentage of Dehydration and Ability to do Work:\n% of dehydration = % of work possible\n\n0% = 100%\n\n5% = 75%\n\n10% = 50%\n\n15% = 25%\n\n20% = 0%\n(possible death)\n\nWater is the third priority whether you find yourself at the ocean or in a snow storm. I ought to mention at this point that woodsmen and hunters sometimes find themselves uncomfortable and a little under the weather a day or two after the beginning of a trip. Often thi

if time is proportional to the square of the distance then you can write:\nt is proportional to d^2\nthen: \n3 seconds is proportional to 10^2\nSo \nx seconds is proportional to 20^2\n3-----> 100\nx------>400\nx= (400x3)/100\nx= 12 seconds

Yes, defensive three seconds. If you aren't within arms length of an offensive player in a defensive position (knees bent, protecting the post, etc.) you will be called for defensive three seconds. The penalty is one technical foul shot for the offensive team and the ball in a sideline out of bounds.
