best of luck

What is answer on this test? =)

0 250

So....., how get this answer? Explain, please. =)

If the plane flies at speed 40, it will reach required height in 250 seconds, i.e. it will do it in time (less, than 500), and there are no time when it exceeded the speed limit (when passengers have their ears blocked). So, mintime = 0. Maxtime is 250, because the plane can fly all the way at speed = 40 + EPS :)

Thank you very mutch!!! AC! =)
And just for fun tests:

x  ==    10
Test #2
h  == 10000 &&
t2 == 500 &&
Vm ==    50  &&
x  ==    9
Test #3
h  == 10000 &&
t2 == 500  &&
Vm ==    50   &&
x  ==    11
Test #4
h  == 10000 &&
t2 == 500  &&

x  == 20
Test #5
h  == 10000  &&
t2 == 500  &&
Vm ==    50 &&
x  == 19
Test #6
h  == 10000  &&
t2 == 500  &&
Vm ==    50 &&
x  == 21
ans: 0.000000000000000 476.190476190476200

What does the EPS mean? How much it must be?

EPS is very small positive number.
For example, you may assume EPS = 10^-2011

Thank you very much! But I didn't think that it must be SO small.

Hey there,
Is it possible for you to explain the last one.
why is it 476..19....?

Thanks
