Answer:
Amount of time would be greater than 95 minutes
Step-by-step explanation:
We are told that machine B can pack 11 boxes per minute.
Thus, this is 11x where x represents number of minutes.
We are told that the factory revives an order of over 1100 boxes and that it had already packed 55.
Thus,the inequality equation is;
11x + 55 > 1100
Solving this;
11x > 1100 - 55
11x > 1045
x > 1045/11
x > 95 minutes
Answer:
11 hours
