If Rael and Avery work together on a project, they will complete it in 5 days. If Avery were to work with Ethan on the same project, they will take a day longer. If Ethan and Isaiah work together, they will take 160% more time than Rael and Avery. If Rael and Isaiah were to work together, how many more days will they take to complete the project compared to Avery and Ethan working together?
Time taken by Rael and Avery in percent = 100%
Time taken by Ethan and Isaiah = 100% + 160% = 260%

Time taken by Rael and Avery = 5 days ---- (1)
Time taken by Avery and Ethan = 6 days ---- (2)
Time taken by Ethan and Isaiah = 260% x 5 = 13 days ---- (3)

(1) + (2) + (3)
Rael + Avery + Avery + Ethan + Ethan + Isaiah → 5 + 6 + 13 = 24 days
Rael + 2 (Avery + Ethan) + Isaiah → 24 days
Rael + Isaiah + 2 x 6 → 24 days
Rael + Isaiah → 24 - 12 = 12 days

More days to complete the project for Rael and Isaiah compared to Avery and Ethan
= 12 - 6
= 6

Answer(s): 6
