Another way to say 2 coats is
to paint the fence twice
Also, that is the same as painting
2 identical fences
---------------
Tom's rate is:
= ( 1 fence ) / ( 8 hrs )
Huck's rate is:
= ( 1 fence ) / ( 5 hrs )
---------------------------
Let = the time in hrs for them
to paint 2 fences
= ( 2 fences ) / ( t hrs )
---------------------------

Multiply both sides by

It will take them 6.154 hrs
