The worlds first riddle!

Thanks for the idea CalamityJane

I have just had an important meeting interrupted by the news that the Francis fan club are revolting…..I mean that in a good way; it's good to see such mirth at my obvious discomfort……That's better I had my pants in a bunch, but it is all straightened out now.



Thanks for the heads up TTH; as for you C-J, you have some moxy to incite a riot. I've got your number lady. ..and I like those figures.


Back to the Francis uprising;


My question:

Now; Nürnberg is approximately 90 miles due west of Prague. How much sooner would a person in Prague first see the rising sun than a person in Nürnberg.


(Even the casual reader will note: 90 miles)



1. Both persons almost see the sunrise at the same time sine they are at the same time zone.

2. the speed of the rotation of the earth is 1 revolution per day.
1 revolution = the perimeter of the earth= 2 Pi r
r=6.4x10^3 km is the radius of the earth
=> 1 revolution= 2 x 3.14 x 6.4x10^3
=40192 km

Therefore the speed of the earth is:
t= (40192/ 24) km/hr=1675 km/hr= (1675/1.609) mile/3600 second= .2891 mile/sec

1 mile=1.609 km; 1 hour= 3600 seconds.

We are given that the distance between this two cities is 90 miles, so after T seconds the person on the west side will see the sunrise:
T= 90 miles / .2891 mile/sec = 311 seconds
=5.2 minutes

So the person on the east side will see the rising sun about 5.2 minutes sooner than the one on the west side.






Francis re-wrote the question:

"Distance from Prague to Nürnberg is 250 kilometers or 155 miles

Try, Try (my, my!).

The reason I reminded you about the sunrise is that I was expecting this.

Your solution is good for some places on the equator.

But not for Prague, which is 50° 05' 19" North. You can check that there the tangential speed is not the same. So, I avoided the trigonometric calculation to establish the perimeter at that point and did it by the coordinates.

Sorry to interrupt your important meeting and thanks to my fan club.

Okay, I think I get it now < these guys look kinda snuggly huh

im at san jose state university....i visited berkeley lab on wednesday, going to visit livermore on thursday

2 8 20 28 50 82 126 are the numbers of stable protons or neutrons in atomic nuclei

thanks, i am enjoying myself and im not planning on getting contaminated

Oh yeah! What about these bananas, were you expecting that?


"Your solution is good for some places on the equator."

Excuse me pal, but every Texan knows Texas is the center of the universe and all calculations take that fact into account; ok?


"But not for Prague, which is 50° 05' 19" North. You can check that there the tangential speed is not the same. So, I avoided the trigonometric calculation to establish the perimeter at that point and did it by the coordinates."

Say what! This ain't no geography thread; who knows where Prague is, is it east of the Bronx?


"thanks to my fan club"


This I was not expecting…Even though C-J was made in Europe, I expect she came over to escape the war; many intelligent people did…….. Then the second world war came…Well you know the rest of the story: Alvin York was a United States soldier, famous for his heroism in World War I. He lived near Texas.




In an effort to placate our continental cousins, today's conundrum is in foreign speed.

My car travels at 80 kilometers per hour for 40 kilometers, 72 kilometers per hour for 48 kilometers, and then 96 kilometers per hour for 32 kilometers.


What is my average rate of speed over the entire trip




4t ;-)

[4t] double this you'll get the answer.

Does he mean WWI?
I will keep a lot of warm vulgarity to myself now; after all, I was trained to speak softly (as reassured by my loving daughter).

80 kpm

half the average speed winks

Rap

Are you saying I should take a nap

No, TTH, he's giving you 4 (four) t (ty) = 40 winks

I'm back. Turns out I was in London when the terrorist thing happened. I never watched TV or read a paper on our trip; so I was unaware of what was going on. I had heard there was some sort of activity, but I didn't know the extent.

I didn't see answers posted for these questions:

If there are 15 stairs and you can climb them either one at a time or two at a time only;

How many different ways can you climb the 15 steps?

C(15,0) + C(14,1) + C(13,2) + C(12,3) + C(11,4) + C(10,5) + C(9,6) + C(18,7) = 987

What a flight; the Boeing 747 super jet left Los Angeles and flew with the wind for four hours, landing at Washington D.C. 2400 miles away.

Later I returned to Los Angeles in five hours over the same route and against the same wind.

What was the cruising speed of the jet And what was the wind speed?

J = 9W
4(J+W) = 2400
W = 60mph
J = 540mph

A little help here please; today I made an ice sculpture, out in the open air, then the sun (yes, remember that) came out and it not surprisingly it began to melt.

Melting at rate of one-half its weight per hour. After 8 hours its weight is 5/16 lbs.

What was the original weight of the sculpture?

2^8 * 5/16 = 80 lbs.

----------

There were three red flags, three blue flags, and three white flags. A signal is made by raising exactly three flags on a pole.

Each flag may be raised into one of four vertical positions on the pole. All three flags may be the same color, or there may be just two of the same color, or all three may be different colors.

How many different signals may be made under these conditions?

C(4,3) * [3 * (3!/3! + 3!/2! + 3!/2!) + 3!] = 108

raprap notes that the ordered numbers begin with f making 42 next.

The differences between each number is 1^2, 3^2, 1^2. 5^2, 1^2 so I fancy 7^2 ie. 90 next. Don't ask about the cubes, I am an idiot.

Then I would say he has an eyelid problem
Welcome back mark

epenthesis
You are an idiot?, you can't be because I am an idiot. Well some of the time but others may say most of the time

Can there be more than one idiot

He wanted to say hi

C-J that is funny!



I am sorry C-J there has been the most awful mix-up, I was of cause referring to:

The Franco-Prussian War (July 19, 1870 - May 10, 1871) was declared by France on Prussia, which was backed by the North German Confederation and the south German states of Baden, Württemberg and Bavaria. The conflict marked the culmination of tension between the two powers following Prussia's rise to dominance in Germany, which before 1870 was still a loose federation of independent territories.

Hi Mark, good to see you back. I hope you and the family had a great time in England town. Did you get to see Buckingham House and Westminster Palace?

I am sure you are right with your answers; but I will in all fairness check.


Speed trial:


Francis: [4t] (40) double this you'll get the answer. = 80


Rap: 80 kpm


half the average speed winks



C-J: 4 (four) t (ty) = 40 winks




I am getting a case of the screaming doubts because my answer to the speed trial is not what you guys have ALL come up with.

This is what I have:



Let d1= 40km, s1= 80km/hr, need time t1 hr
so t1= d1/ s1= 40/ 80= 1/2 hr

Let d2= 48km s2= 72km/hr, need time t2 hr
t2= 48/72= 2/3 hr

Let d3= 32 km, s3= 96 km/hr need time t3
t3= d3/s3= 32/ 96= 1/3 hr

So we need to spend T= t1+t2+t3= 1/2 + 2/3 + 1/3= 3/6+ 4/6+ 2/6= 9/6= 3/2=1.5 hrs to run the total distance D= d1 + d2+ d3= 40+ 48+ 32=130 km

Therefore the average speed is
S= D/ T= 130 / 1.5= 260/3 km/hr ( or approximately equal to 86.67 km/hr).


So, am I a freekin genius or a sad misguided fool? The jury is still out.

Good lad, always use protection!!! :wink:


Anyone seen Etc about; or has the devil got her tongue?

Better get another calculator, Try: 40+ 48+ 32=120 km
