Food for Thought You are planning a dinner party for yourself and five guests. This is your menu: Onion soup with French bread Roast chicken with boiled mixed vegetables Pie with hot chocolate sauce You have arranged to go to a Halaqa before the dinner, and afterward the six of you are going to a soccer game. You can prepare the ingredients for the meal before you leave for the Halaqa, but will you be able to get back in time to cook and serve the dinner? Will you and your guests get to the game on time? Your problem is to estimate the shortest time in which you could cook, serve, and eat the meal. (The clearing and washing can wait until the next morning.) YUK! The following are your best estimates of the times needed to complete the various activities associated with the dinner: 30 minutes 10 minutes 45 minutes 25 minutes Cooking the onion soup Warming the bread in the oven Roasting the chicken in the oven Boiling the vegetables Warming the pie in the oven Cooking the chocolate sauce Serving and eating the soup Serving and eating the chicken Serving and eating the apple pie 15 minutes 40 minutes 20 minutes 25 minutes 15 minutes You are planning to serve Green Tea - Moroccan style. You need 35 minutes to prepare the tea. You intend to serve the tea with the chicken. Incidentally, you have only one pot to use for boiling the soup, the mixed vegetables, and the chocolate sauce. (You can assume that it takes no time at all to rinse it.) Also, your oven can hold only one item at a time. How quickly can you cook, serve, and consume the meal? You should be able to get the answer in 15 to 20 minutes, but take a little longer to think about how you got there. How, for instance, would you persuade somebody that the answer you have found really is the shortest time
