It is your sister's birthday and you are preparing a family meal. the joint of meat needs to be cooked for 30 minutes per 500 g plus an extra 20 minutes. how long will it take to cook a joint of meat weighing 2.5

Time taken to cook 500 g or half kg of meat =30 minutes

time taken to cook 1 kg of meat = 30/0.5 = 60 minutes

time taken to cook 2.5 kg of meat = 2.5* 60 = 150 minutes

Now extra 20 minutes are also required for cooking.

So total time taken to cook 2.5 kg of meat = 150 minutes + 20 minutes

=170 minutes

Answer is time taken to cook a joint of meat weighing 2.5 kg is 170 minutes.
