Question 377558: One painter can paint a house in 40 hours and another painter can paint the same house in 35 hours. How long will it take them to paint the house if they work together? -Thanks a lot! Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! t=time it will take them to paint the house if they work together.
1/40 + 1/35 = 1/t
7t+8t=280 multiply each side by 280t
15t=280
t=56/3 hrs.
