conversations.value: Can you break down the solution for me for this math problem: Delaney has to catch a bus that leaves at 8:00. a.m to school every day. He always takes 30 minutes to reach the pick-up point from his home. One day he woke up late and left his home at 7:50. How much time did he miss the bus by when he reached the pick-up point?
conversations.from: assistant
conversations.value: If he left his home at 7:50 a.m. and the distance to the pick-up point is 30 minutes away, he arrived at the pick-up point at 7:50 + 30 minutes = 8:20 a.m.
  If the bus leaves at 8:00 a.m. every day, then Delaney was 8:20 a.m. - 8:00 a.m. = 20 minutes late when the bus had already left.
