Answer: He should start cooking the turkey at 12:55
Explanation:
Hi, to solve this problem we have to analyze the information given:
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 .
