conversations.value: Break down this math problem: To earn an airplane pilot certificate, Sangita is required to fly 1,500 hours. She has already completed 50 hours of day flying, 9 hours of night flying, and 121 hours flying cross-country. To meet her goal in exactly 6 months, how many hours per month must Sangita fly?
conversations.from: assistant
conversations.value: Sangita has already flown for a total of 50 hours + 9 hours + 121 hours = 180 hours
  The flight time she has remaining is 1500 hours - 180 hours = 1320 hours
  Sangita's monthly target must therefore be 1320 hours / 6 months = 220 hours/month
