### Writing Project 2:

# A work word problem

If Adam and Beth would paint the room together, they would need 5 hours. If Adam
and Cindy would paint it together, they would need only 4 hours. If Beth and Cindy
would paint it together, they would need only 3 hours. How long do they need if
all three work together?

Generalize this kind of problem for 4 persons, and solve this as well.
