If Raeann and Noah work together on a project, they will complete it in 5 days. If Noah were to work with Zoey on the same project, they will take a day longer. If Zoey and Joseph work together, they will take 60% more time than Raeann and Noah. If Raeann and Joseph were to work together, how many more days will they take to complete the project compared to Noah and Zoey working together?
Time taken by Raeann and Noah in percent = 100%
Time taken by Zoey and Joseph = 100% + 60% = 160%

Time taken by Raeann and Noah = 5 days ---- (1)
Time taken by Noah and Zoey = 6 days ---- (2)
Time taken by Zoey and Joseph = 160% x 5 = 8 days ---- (3)

(1) + (2) + (3)
Raeann + Noah + Noah + Zoey + Zoey + Joseph → 5 + 6 + 8 = 19 days
Raeann + 2 (Noah + Zoey) + Joseph → 19 days
Raeann + Joseph + 2 x 6 → 19 days
Raeann + Joseph → 19 - 12 = 7 days

More days to complete the project for Raeann and Joseph compared to Noah and Zoey
= 7 - 6
= 1
