Given
1) Height of Floor  = 4m
   so height between 36 and 96 floor
               But take 96 - 1
Since the height of the last floor can be neglected because it is a time domain problem

so ,  height = ( 95 - 36 ) * 4
                   =( 59 ) * 4
                   =236 m

2 ) time taken to reach the height
                   time = total height  / height reached every hour
                            = 236 / 3
                             =  78 hours and 20 minutes
