Question

Jenny is cooking a chicken for dinner. A chicken needs to be cooked for 40 mins per kilogram, plus an extra 20 mins.

How long will it take to cook a chicken weighing 3 kilograms?

Answer 1

If it is 3kg, it will be:
40mins x 3 = 120mins
Add the extra 20 mins, it will be 140 mins. This equates to two hours and 20 minutes.

Answer 2

Answer: The required time is 2 hrs 20 mins.

Step-by-step explanation: Given that Jenny is cooking a chicken for dinner. A chicken needs to be cooked for 40 minutes per kilograms plus an extra 20 mins.

We are to find the time duration to cook a chicken weighing 3 kilograms.

We have

time required to cook 1 kilogram of chicken = 40 mins.

So, time required to cook 3 kilograms of chicken will be

`40*3=120~\textup{mins}.`

Since there is an additional time of 20 mins, so the total time required to cook 3 kilograms of chicken will be

`120+20=140~\textup{mins}=2~\textup{hrs}~20~\textup{mins}.`

Thus, the required time is 2 hrs 20 mins.
