But think about MAX time, it also can be real, not only MIN.sdlcj Solution [2] // Problem 1885. Passenger Comfort 11 Mar 2012 17:44 Note that : print the double is ok!

Passenger Comfort 13 Jun 2013 01:11 Solution is very simple but I couldn`t firstly find it. It is a set of equations, everybody learned it at school. Simply try to solve this: y+z=t and v*y+x*z=h, where Y is MIN time and Z is t-MIN time. Try to find MAX by yourself. Sorry for my awful English.

Explain, please. =) bsu.mmf.team Re: test [7] // Problem 1885. Passenger Comfort 31 Oct 2011 13:01 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 :) Edited by author 31.10.2011 13:02 IgorKoval(from Pskov) Re: test [3] // Problem 1885.

How much it must be? bsu.mmf.team Re: test [1] // Problem 1885. Passenger Comfort 1 Nov 2011 20:49 EPS is very small positive number. For example, you may assume EPS = 10^-2011 GERDA Re: test // Problem 1885. Passenger Comfort 3 Nov 2011 09:26 Thank you very much! But I didn't think that it must be SO small.
