In 1 minute,
Aimee can pack = 1/6 th of box
Brianna can pack = 1/5 th of box
Combined can pack = 1/6 + 1/5 = 11/30 box per minute
--> 1 box can be packed in 30/11 minutes
--> 110 boxes = 110*30/11 = 300 minutes = 5 hours
IMO Option D
Pls Hit kudos if you like the solution

Aimee & Brianna together pack \(\frac{1}{6} + \frac{1}{5} = \frac{11}{30}\) boxes /min = 22 boxes in an hour
Time taken = \(\frac{110}{22}\) = 5 hours
IMO D

A takes 6 mins to pack a box
B takes 5 mins to pack a box
in 30 mins(6x5) they must have packed 11 boxes .So to pack 110 boxes they need 10*30 mins= 300/60= 5 hours
B takes 5 mins to pack a box
in 30 mins(6x5) they must have packed 11 boxes .So to pack 110 boxes they need 10*30 mins= 300/60= 5 hours

Together : A*B/A+B = 6*5/6+5 = 30/11
For 110 Boxes = 30/11*110 =300
convert it into hours as the answer choices are in hours = 300/60 = 5 hrs Answer choice D
Hope it's correct.
