I love JCM's ability to see the puzzle in an easy to comprehend manner.

This is a good one for you number crunchers:

I'm a four-digit number! My 2nd digit is twice greater than my 3rd. The sum of all my digits is thrice greater than my last digit! The product of my 3rd and 4th digits is 12 times greater than the ratio of my 2nd to 3rd. What am I?
[Off-topic] stephj:
OK Lets throw these lines of C at it. A brute force attack but it works!

int i,a,b,c,d;

for (i=0;i<10000;i++)
{
a=(i/1000);
b=(i/100)%10;
c=(i/10)%10;
d=i%10;

if(c!=0)
if(b==2*c && a+b+c+d==3*d && c*d==12*b/c)
printf("%d\n", i);
}

7638

The four digits excludes 0846 which also works.

The line if (c!=0), prevents the program from throwing a division by zero exception.

Even closer. But after walking five miles south, you would be at the South Pole, and you can't walk west from the South Pole either, you can only walk north!

You actually have to walk file miles south, five miles west then file miles north. When you have finished, you will have covered 15 miles, and you are back exactly where you started.

[Off-topic] 4silvertooth:
Yaa correct.
[Off-topic] stephj:
As mentioned previously, if there was no answer within about 24 hours, I'd cough up the answer.

mercianary's answer of 5 miles north of the South Pole was pretty close, but the correct answer is any point on the line of latitude 5.79577 miles north of the South Pole.

After walking 5 miles south, you are then 0.79577 miles north of the pole. At this distance from the south pole walking five miles west, (or east), will take you in a complete 360 degree circuit of the South Pole, always 0.79577 miles from it. At the end of it, you are at the point that you originally turned, west/east. The remaining five miles north retraces the original five miles south. You are now back where you started.

The inhabitants of a planet's moon, have their own measurement system similar to ours, but based on a unit of length called a 'lunar'.

The lunar was chosen because, when the volume of the moon is expressed in cubic lunars, the result is the same as the surface area of the moon expressed in square lunars.

Their moon has the same diameter as our moon, 2160 miles.

How long is a lunar?
[Off-topic] mazook98:

<<bringing it since 2010>>
[Off-topic] :
Blank blank blank
[Off-topic] 4silvertooth:
Is it 360 miles.

I mean 1 lunar = 360 miles.

As due to the condition.

Surface area of moon = volume.

4 x pi x r² = 4/3 x pi x r³

So r = 3 lunar.

Diameter = 2160 miles so radius = 1080 miles.

1080 miles in 3 lunar will be 1080/3 = 360.

So 1 lunar = 360 miles.

[Off-topic] stephj:
Not really a puzzle, but another one to get the grey matter working, and it reveals an interesting point.

There are two cities, A and B, A being directly north of B.

A plane makes one return trip per day from A to B and back.

On Monday, the weather is completely still and no wind blows.

On Tuesday, there is a steady southerly wind, the plane has a tailwind going out and a headwind coming back.

On Wednesday there is a steady westerly wind, the plane has a crosswind in both directions.

Which day has the least flying time, but what's more why? Flying time ignores the disembarkation and loading at city B.

The plane can fly much faster than the wind can blow.
[Off-topic] Dirk:
I'm going to hazard that the crosswind is faster and it has something to do with the earths rotation as you are flying.

i.e flying between destinations North and South of each other will entail a flight path that is just off of North and South, as your destination will have moved east or west depending on which leg of the journey you are on.

Barking up the wrong tree this time?
[Off-topic] stephj:
Your thinking a bit too hard for this one. We can safely ignore the Coreolis force, as the plane is not travelling fast enough. That only really applies to satellites and missiles.

Winds will have a much greater effect on the plane.
[Off-topic] 4silvertooth:
I think it will take same time on all days. No wind = Headwind - Tailwind = cosine(90° ) <- crosswin in terms of head or tail wind.

[Off-topic] stephj:
It's probably time to put the plane flying from A to B, to bed.

The day with the least flying time is Monday.

If there is any wind blowing at at all in any direction, the return trip takes longer.

(1) If the wind blows S->N, (or N->S it's the same), the assumption is that the tailwind leg will counteract the headwind leg, and they will cancel each other out. In reality they don't. The plane spends less time in the air flying at the higher groundspeed with the tail wind, and more time flying at the lower groundspeed, against the headwind on the return. They always add up to more time than a straight return flight with no wind. If you don't believe me, pick a few values and try it out.

(2) If the wind blows from the side, (it would not affect the forward speed as 4silvertooth pointed out), but the aircraft would be blown off course. It has to fly slightly into the wind to compensate. The resultant groundspeed is the square root of (v*v - w*w) where v is the plane's speed and w is the windspeed, (pythagoras). It is always less than v if w>0

If the wind blows from any other direction the results of 1 and 2 are compounded.

• The Swede keeps dogs as pets.

• The Dane drinks tea.

• The green homeowner drinks coffee.

• The person who smokes Pall Mall rears birds.

• The owner of the yellow house smokes Dunhill.

• The man living in the center house drinks milk.

• The Norwegian lives in the first house.

• The man who smokes Blends lives next to the one who keeps cats.

• The man who keeps the horse lives next to the man who smokes Dunhill.
