when Max and Ruby work togher they 
can build a fence in 11 HOURS 
if max worked alone it would take 
him 24 hrs. how long would it take Ruby
to do alone

max    Ruby     together
1/24 + 1/x  =   1/11
    LCD= 24 X (x) X 11 = 264x
1/24 X(264x) + 1/x X(264x) = 1/11 X(264x)
  CROSS OUT
11x + 264 = 24x
264 = 13x
20.30769 = x

It would take Ruby about 20.3 hrs
alone to build the fence.


Rick can fix a portal gun in 15 hrs
Morrtyu can repair one in 22 hrs
if they work togther how long would it take.

Rick    Morty    togther
1/15  + 1/22   =  1/x
    LCD=15 X 22 X (x) = (330x)
1/15 X (330x) + 1/22 X(330x) =1/x X(330x)
22x=15x=330
37x=330
x=8.918

It would take them around 8.9 hrs
togther.
