You need to make 5 grilled cheese sandwiches. You have a grill that is large enough to toast 2 sandwiches at a time. The sandwic
hes must be toasted one minute on each side. It takes 3 seconds to flip a sandwich and 5 seconds to take one off or put one on the grill. What is the shortest amount of time needed to toast all five sandwiches?
Each sandwich is toasted for 2 minutes and it takes 3 seconds to flip it. The first two sandwiches will be toasted in 2 minutes (toasting) and 6 seconds (flipping). The two will then be switched which will take 10 seconds. The next two will again take 2 minutes and 6 seconds. The final sandwich will take 5 seconds to be placed. The final sandwich will also take 2 minutes to toast and 3 seconds to flip. Total time: 2 + 2 +2 = 6 minutes 6 + 10 + 6 + 3 = 25 seconds Total time is 6 minutes and 25 seconds.
