conversations.value: There are 3 kids waiting for the swings and twice as many kids waiting for the slide. If each kid waits 2 minutes for the swings and 15 seconds for the slide, how many seconds shorter is the shorter wait?
  Work out the solution step by step.
conversations.from: assistant
conversations.value: First find the total wait time for the swings in minutes: 3 kids * 2 minutes/kid = 6 minutes
  Then convert that number to seconds: 6 minutes * 60 seconds/minute = 360 seconds
  Then find the total number of kids waiting for the slide: 3 kids * 2 = 6 kids
  Then find the total wait time for the slide: 15 seconds/kid * 6 kids = 90 seconds
  Then subtract the total wait for the slide from the total wait for the swings to find the difference: 360 seconds - 90 seconds = 270 seconds
