If Jeremiah and Jonathan work together on a project, they will complete it in 5 days. If Jonathan were to work with Raeann on the same project, they will take a day longer. If Raeann and Risa work together, they will take 120% more time than Jeremiah and Jonathan. If Jeremiah and Risa were to work together, how many more days will they take to complete the project compared to Jonathan and Raeann working together?
Time taken by Jeremiah and Jonathan in percent = 100%
Time taken by Raeann and Risa = 100% + 120% = 220%

Time taken by Jeremiah and Jonathan = 5 days ---- (1)
Time taken by Jonathan and Raeann = 6 days ---- (2)
Time taken by Raeann and Risa = 220% x 5 = 11 days ---- (3)

(1) + (2) + (3)
Jeremiah + Jonathan + Jonathan + Raeann + Raeann + Risa → 5 + 6 + 11 = 22 days
Jeremiah + 2 (Jonathan + Raeann) + Risa → 22 days
Jeremiah + Risa + 2 x 6 → 22 days
Jeremiah + Risa → 22 - 12 = 10 days

More days to complete the project for Jeremiah and Risa compared to Jonathan and Raeann
= 10 - 6
= 4

Answer(s): 4
