Answer:
51.69 hours (see explanation)
Step-by-step explanation:
This question is simple once you break it down:
84 boxes in 312 hours is a rate, so it can be shown in fraction form:
84 boxes / 312 hours
Now to figure out how long it takes to unpack those 192 boxes, just multiply:
192 x 84/312
(192 x 84) / 312
16128 / 312
Now, just divide the numbers:
16128 ÷ 312 = 51.69 hours
