Question 1174614: A group of friends nailed it when it comes to video editing. Ana can edit a video in 7 days alone, while Shereene can edit the same video in 5 days. If Shereene and Anna can edit the same video at most twice as faster as Eufemia does alone, how long will it take if Anna and Eufemia edit the same video together?

This passage " . . . at most twice as faster as . . . " is FAR BEYOND of anybody's imagination . . .

Ana can edit a video in 7 days alone,
Shereene can edit the same video in 5 days.
:
Find how long it takes a and s to do it together
let t = time required when they work together
let the completed job = 1 + = 1
multiply by 35, cancel the denominators
5t + 7t = 35
12t = 35
t = 35/12
t = 2.917 days working together
:
:
If Shereene and Anna can edit the same video at most twice as fast as Eufemia does alone,
That means it takes e: 2*2.917 = 5.833 days for e to do it alone
:
how long will it take if Anna and Eufemia edit the same video together?
let s = time required when a and e work together + = 1
multiply by 40.833, cancel the denominators
5.833s + 7s = 40.833
12.833s = 40.833
s = 40.833/12.833
s = 3.182 days, a and e working together
