Answer:
400 boxes
7 minutes
Step-by-step explanation:
for 224 boxes. --------> 2.8 min (168 sec)
so for 80 box -------> 1 min
80*5 box ------> 1*5 min
400 box -------> 5 min
So they will pack 400 boxes in 5 minutes.
224 boxes -------> 2.8 min
560 boxes -------> 560*2.8/224
(cross multiplication)
560 boxes --------> 7 min
So 7 min will be required to pack 560 boxes
