If 8 machines make 8 plugs in 8 minutes the rate is 1 plug per minute per machine. In this case, you need double or 2 times the number so the answer is 90x 2 = 180 minutes.

have a great day!

the ans is 180 minutes.

Step-by-step explanation:

if 8 machines took 8 minutes to make 8 plugs it means each machine took 1 minute to make 1 plug.So if there is 90 machines you need 90 × 2 = 180 minutes to make 180 plugs
