A father and his son are working together to paint a picket fence. The father can paint a board in 0.04 hours, while his son takes 0.05 hours for each board. What is the combined rate in boards/ hour for the father and son team to paint the fence?
-------------
0.04 hr/board = 25 boards/hr
0.05 hr/board = 20 boards/hr
20+25 = 45 boards/hr
