Let's break down the problem step by step:
- Nine identical machines can stitch 27 jerseys in four minutes.
- This means that one machine can stitch (27 jerseys) / (9 machines) = 3 jerseys in four minutes.
- To find out how many jerseys one machine can stitch in one minute, we divide by 4 (since there are 4 minutes in one minute): 3 jerseys / 4 = 0.75 jerseys per minute per machine.
Now, we want to determine how many minutes it would take for 4 such machines to stitch 60 jerseys:
- First, calculate how many jerseys 4 machines can stitch in one minute: 4 machines * 0.75 jerseys per minute per machine = 3 jerseys per minute for 4 machines.
- To find out how many minutes it takes to stitch 60 jerseys at this rate, divide 60 jerseys by the rate of 3 jerseys per minute: 60 jerseys / (3 jerseys per minute) = 20 minutes.
So, it would take 4 machines 20 minutes to stitch 60 jerseys.
