How about this one -

You travel to america at 100km/h. You then travel back at a constant speed. The average speed for the entire journey is 50km/h. What was your speed in returning from america?

heh heh heh
arent i funny

33km/h?

33km/h?

Nein

x = 0.9r

10x = 9.9r

9x = 9.9r - 0.9r

9x = 9

x = 9/9

x = 1

*cough*

try encriptions mate --- read dan browns digital fortress...

Can't tell if srs?

 

[TheCenturion]

Nein

33.3r km/h?

*cough*

nothing wrong with that?

 

[Jupiter]

*cough*

0.9 x 10 = 9...

0.9r x10 = 9.9r

j. 'i' is for current. Stupid mathematical types!

 

[Jupiter]

33.3r km/h?

nope, to give you a clue, its a bit of a silly answer

 

[Darg]

x = 0.9r

10x = 9.9r

10x = 9.0r not 9.9r

[[FnG]magnolia]

0.9 x 10 = 9...

0.9r x10 = 9.9r

Oh God, not this again. Seriously. But wait - what if the equation was on a conveyor belt?

 

[SpeedFreak]

33.3r km/h?

faster

 

[Jupiter]

10x = 9.0r not 9.9r

Thecenturion is completely right. Use a calculator if you must.

0.9 x 10 is 9.
0.9>R< x 10 is 9.9r

 

[Antelopethy]

Thecenturion is completely right. Use a calculator if you must.

0.9 x 10 is 9.
0.9>R< x 10 is 9.9r

I guess I'm just being trolled?

Greater minds than anyone posting on this board have debated back and forth over this 0.9r=1 concept and never reached an agreed conclusion, it's not something that's going to be miraculously solved by an argument over whether 0.9r multiplied by 10 is 9 or 9.9r.
