Question

Belle is going to make chili for a football party. It will take 1 hour and 10 minutes to prepare all the ingredients and assemble them in the pot. Then, the chili will need to simmer for 1 hour and 40 minutes. What is the latest time Belle can start preparing the ingredients if the chili needs to be ready at 4:00 P. M. ?

Answer 1

1:10pm

Explanation:

1st, you add all the time needed to make the chili & cook it.

1 hour + 10 minutes + 1 hour + 40 minutes = 2 hours & 50 minutes.

Now you work backwards from 4:00pm.

You go back 2 hours & you would be at 2:00pm

Now you go back another 50 minutes & you would be at 1:10pm

To double check, you can add 2 hours & 50 minutes to 1:10pm & you would get 4:00pm
