Portion A of program P takes 'x' seconds; portion B takes 'y' seconds. 'x + y = 100'. A is wholly sequential, while B is wholly parallel. With an infinite number of processors, we get a speedup of 's'. It takes 5 2/3 imaginary processors (6 real processors) to achieve a speedup of at least 's/2'. What are the values of 'x' and 'y'? (They are integers).
