Tina can paint a room 1.5 times faster than Joey can. If they work together, they can paint a room in 6 hours. How long would it take the slower person working alone to paint the room?
So, the rate is 1 job / hours, so: 1/n + 1/1.5n = 1/6 We'll make the denominator 3n: 3/3n + 2/3n = 1/6 5/3n = 1/6 Cross multiply: 3n = 30 n = 10 It will take the slower person 10 hours to complete the room.
