conversations.value: Can you walk me through the solution of: Every 10 seconds, there is a car collision, and every 20 seconds there is a big crash. How many accidents overall will happen in 4 minutes?
conversations.from: assistant
conversations.value: 1 minute is 60 seconds, so 4 minutes is 4 * 60 = 240 seconds.
  During this time there would be 240 / 20 = 12 big crashes.
  And also 240 / 10 = 24 car collisions.
  So in total during 4 minutes there would be 12 + 24 = 36 accidents.
