Siddarth Luthra Characters: 3,610 Essay for December 9th Whether its planning an agenda for the rest of your day or planning out the construction for a building, planning is an important part of life. Planning helps people get something done on time and usually helps people stay on task. I am the designer of an airport and I need to decide how many runways my airport is supposed to contain. According to my supervisors the airport can handle a total of 50 takeoffs and landings at most. Additionally, during peak hours the number of landings is 50% more than the number of takeoffs and vice versa. Also, the runways must be long and a takeoff can occur from the middle of the run away, a landing can occur from the end to the middle of the runway. The time between consecutive landings must be six minutes and the time between consecutive takeoffs must be four minutes. To solve this "runway problem" I strived to find the number of takeoffs and landings that can occur at peak hours. Since, there can be 50 takeoffs and landings total at a peak hour and either the takeoffs or landings have to be 50% more than one or the other, I started to find combinations of numbers that add up to 50. When going through different combinations of numbers, I also looked for numbers that followed the rule of 50% more takeoffs than landings or vice versa. I then concluded that 20 landings or takeoffs and 30 landings and takeoffs was the right answer. This is because 30 is equal to 20 plus 50% of 20. Once I found how many landings and takeoffs can occur in a peak hour, I then decided to solve for how many runways are needed for 20 landings and 30 takeoffs. I realized the takeoffs and landings can occur on the same runway at the same time. Using the restraint given from my supervisors about there being six minutes in between every landing and four minutes between every takeoff, I multiplied the number of times between each event by the number of events I came up with in a peak hour. This was 20 landings times six minutes which equals 120 minutes of landings that had to be done in a peak hour. Also, I had to multiply 30 takeoffs with four minutes which also equals 120 minutes of takeoffs. Since an hour is 60 minutes and 120 minutes divided by two runways is 60 minutes, we need at least two runways. Since the number of runways was solved for 20 landings and 30 takeoffs per runway, the number of runways was also needed to be solved for the vice versa peak hours, where there would be 30 takeoffs and 20 landings. I multiplied the 30 landings with six minutes and got 180 minutes of landings in the hour minutes and the 20 takeoffs with four minutes and got 80 minutes of takeoffs in the hour. Since there are more landings there should be more runways for the landings which can also handle the 80 minutes of takeoffs easily. To get to 60 minutes I divided the 180 minutes of landings by three runways and got 60 minutes. Therefore, there should be three runways. I believe that my plan will work because there will be more than enough runways with peak hours when there will be 20 landings and 30 takeoffs per runway. Additionally, there will be enough runways for exactly 180 minutes ofclandings during peak hours with 30 landings and 20 takeoffs per runway. Assuming that usually there will be no technical difficulties this plan will most definitely work. This plan may also work with a few difficulties because there is extra time and runways for certain peak hours and certain events especially the takeoffs. During peak hours where there will be 20 landings and 30 takeoffs per runway there will be an extra runway for difficulties when problems occur.
