HOW WAS MATHS PAPER 2?????

[yannickhow]

I was easy this one, may be i lost abut 3pts in this paper 2

 

[alay]

i think u calculated 45metres/sec...

 

[Snowberry]

Mine went quite well. I lost only around 7 points.

At first I thought that the question on pyramid was hard but when I did it, i found it really easy. I could not do the last part in the Graph. :S

 

[yudish9]

in sectionA there was a question on angles....the very first part ..has it said POLYGON OR PENTAGON???

 

[Shiki Misaki]

The first question..I think.. they asked about a polygon of 10 sides.. we were asked to find the interior angle..
As for the part which followed, there Pentagon was mentioned.

@ usama1993 :: The speed of the plane should be about 300 km/h.. That's the correct answer !

A plane cannot fly at 45km/h.. Its too slow. Compare it wid a speed of a car.

I got 300 and something km/h too.

I got it all wrong..i misread it and thought that it was a pentagon....pppppppppppfffffffffffff

 

[yudish9]

What time had you got for the plane???

 

[Shiki Misaki]

For the flight from P to Q? I don't remember the exact value. :S Sorry.

 

[yudish9]

i think i got around 14 15--14 25...right???

 

[Shiki Misaki]

Well yeah, it is 14 00 and something.

 

[bamteck]

The formula to use for the polygon to calculate the angle :: (n-2)180/n

 

[yudish9]

The formula to use for the polygon to calculate the angle :: (n-2)180/n

ya...its right ..i knew it but pfff i did not read the ques well

 

[Shiki Misaki]

The formula is (n-2) x 180 and not (n-2)180/n !

 

[yudish9]

yes i think the angle was requires so it must be (N-2) X 180

 

[bamteck]

(n-2)180/n ;; this one is correct ! I checked it!

 

[Shiki Misaki]

You're sure about that? :S :S :S

 

[Shiki Misaki]

Oh shit! Yeah, i got that.

I calculated the sum of all the interior angles. Damn!

So, (n-2) x 180 is for the interior angles and (n-2) x 180/n is for only one interior angle.

Silly mistake! I hate myself for that.

A plane cannot fly at 45km/h.. Its too slow. Compare it wid a speed of a car.

then how the hell did the plane take 36 minutes and blah blah blah seconds to travel from P to Q it's just 17 kilometers away, if the answer is 300 km/h then it would take 0.057 hours, which is 3.42 minutes, it is stated that it took 36 minutes.
