If Maya and Jeremiah work together on a project, they will complete it in 8 days. If Jeremiah were to work with Jayden on the same project, they will take a day longer. If Jayden and Roshel work together, they will take 50% more time than Maya and Jeremiah. If Maya and Roshel were to work together, how many more days will they take to complete the project compared to Jeremiah and Jayden working together?
Time taken by Maya and Jeremiah in percent = 100%
Time taken by Jayden and Roshel = 100% + 50% = 150%

Time taken by Maya and Jeremiah = 8 days ---- (1)
Time taken by Jeremiah and Jayden = 9 days ---- (2)
Time taken by Jayden and Roshel = 150% x 8 = 12 days ---- (3)

(1) + (2) + (3)
Maya + Jeremiah + Jeremiah + Jayden + Jayden + Roshel → 8 + 9 + 12 = 29 days
Maya + 2 (Jeremiah + Jayden) + Roshel → 29 days
Maya + Roshel + 2 x 9 → 29 days
Maya + Roshel → 29 - 18 = 11 days

More days to complete the project for Maya and Roshel compared to Jeremiah and Jayden
= 11 - 9
= 2

Answer(s): 2
