Adam buys a bigger turkey than he needs. The turkey he buys weighs 7 kg. Below are the cooking instructions for the turkey. Cooking Instructions Weight Cooking times Less than 4 kg Allow 20 minutes per kg, plus 70 minutes Over 4 kg Allow 20 minutes per kg, plus 90 minutes Always leave the turkey to rest for 30 minutes before carving, to retain the moisture. He plans to carve the turkey at 17:15. What time should he start cooking the turkey?

Given:
7 kg turkey

cooking time: over 4kg;
allow 20 minutes per kg plus 90 minutes
leave to rest for 30 minutes before carving

20 * 7 = 140 minutes + 90 minutes = 230 minutes cooking time
230 minutes + 30 minutes to rest = 300 minutes all in all

300 minutes ÷ 60 minutes = 5 hours

If he plans to carve the turkey at 17:15,

17:15 - 5:00 = 12:15

then he should cook the turkey at 12:15

Answer: He should start cooking the turkey at 12:55

Step-by-step explanation:

Hi, to solve this problem we have to analyze the information given:

Turkey weight: 7kg

So, we have to follow the cooking instructions for over 4kg:

20 minutes per kg + 90 minutes + 30 minutes (rest)

Now we have to multiply the weight of the turkey by the minutes per kg.

(20 x 7 )+90 + 30 = 260 min

260 minutes * 1hr/60 minutes = 4 hours 20 minutes

And finally, if he plans to carve the turkey at 17:15

17:15 -4:20 =12:55

He should start cooking the turkey at 12:55 .
