90/(V-3) - 90/(V+3) = .5

You get V= 33

So you should get the time s 2.5

for question 2

2) x^4 should be greatest and it should be 3^4 and the rest y^4

so should be between 3 and 6

B

I copy those using SnagIt, save them in mspaint to bmp and just save another jpg copy of it using picasa.


trivikram, in the 2nd problem, don't they need perfect quads. of x and y to sum upto 100?

f you see the question he never mentioned that x,y are integers

So there might be some number between 3 and 6 sufficing the condition for y and another number for x

If you solve the equation in my earlier post you get V^2 =1089

So V is approximately 33

Ok, so I now know how to do the algebra and figure out V = 33. However, my method took FOREVER! On a test I would have wasted 4 min on just the calculation. If you have any shortcut that I'm missing please let me know. I basically set it at 90/(v-3) = .5 - 90/(v+3) and went from there but man it took a while...
