<PRE><B>Question 1148398</B>
Tatum can paint 4 walls in 45 minutes and Joe can paint 3 walls in 37 minutes.
 If they decide to paint together, how many walls could they paint in one hour?
:
T paints: {{{45/4}}} = 1 wall in 11.25 min
J paints: {{{37/3}}} = 1 wall in 12.33 min
:
in 60 min T paints {{{60/11.25}}} = 5.33 walls
in 60 min J paints {{{60/12.33}}} = 4.86 walls
-------------------------------------------------
working together they paint:  10.2 walls </PRE>
