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?

  • math -

    What is the rate of each working?
    Sally=house/4hrs
    John=house/6hours

    combined rate= Sally rate + john rate
    = house(1/4 + 1/6)=house (10/24)

    housetogether=combindedrate(time

    time=house/house(10/24)=24/10=2.4 hrs.
