conversations.value: First find the time it takes Jill to run up the hill: 900 feet / 9 feet/second = 100 seconds
  Then find the time it takes Jill to run down the hill: 900 feet / 12 feet/second = 75 seconds
  Then add the two times to find Jill's total time: 100 seconds + 75 seconds = 175 seconds
