I have trouble solving word problems. Can you tell me the best approach to solve this word problem?
If Sally can paint a house in 4 hours, and John can paint the same house in 6 hours, how long will it take for both of them to paint the house together?
What is the rate of each working?
combined rate= Sally rate + john rate
= house(1/4 + 1/6)=house (10/24)
