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

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 .
