Roselyn Jimenez · Answer 1

Time taken by chicken to get cooked = 25 minutes

Time taken by rice to get cooked = 40 minutes

Time taken by green beans to cook = 15 minutes

Time at which all the foods get cooked = 5:33 pm

So, we will subtract the cooking time of each food item from 5:33 to know the time when Tony starts cooking them.

For chicken, he started cooking it by = 5:33-25 = 5:08 pm

For rice, he started cooking at = 5:33-40 = 4:53 pm

For green beans, he started cooking at = 5:33-15 = 5:18 pm

Hence, Tony started cooking chicken at 5:08 pm. He started cooking rice at 4:53 pm and green beans at 5:18 pm.
