Answer: 6hours
Step-by-step explanation:
it will take Nakita 10 hours to get 25 copies of the video ready
Then it takes Nakita 25/10 per hour to get 25 copies ready
it will take Abby 15 hours to get 25 copies of the video ready
Then it takes Abby 25/15 per hour to get 25 copies ready
It is assumed that they are working individually and simultaneously. This means their work rate is additive.
Their combined work rate per hour is
25/10 + 25/15 = 5/2 +5/3
=25/6 per hour
Let x hours be the time it will take them to get 25 videos ready.
It will take them 25/x per hour to get the videos ready
Equating both expressions,
25/x =25/6
25 × x = 25 × 6
x = 6 hours
