Answer:it will it take him 6 minutes to cook the rest.
Step-by-step explanation:
The chef needs to cook a total of 9 potatoes. He has already cooked 7 potatoes. That means that the number of uncooked potatoes left is total number of potatoes - number of cooked potatoes. It becomes
9-7 = 2 potatoes
If each potato takes 3 minutes to cook, this means that 2 potatoes will take 3 minutes × 2 j = 6 minutes
Since there are only 2 potatoes left uncooked, it will it take him 6 minutes to cook the rest.
