Answer 1

We can’t say the answer until we come to know the time it takes for machine to put the caps

Answer 2

Answer: It takes 1.6 hours for the machine to put the cap on 300 bottles.

Step-by-step explanation:

The machine puts caps on 300 bottles in 480 minutes.

So the rate of machine is: rate = job/time which is equal to caps of bottle per minutes.

The time needed to put caps on 300 bottles manually is: time = job /rate which is equal to (bottle×minutes)/60 hours.

(480×60) /(60×300) = 1.6 hours.
