conversations.value: Explain how to solve this math problem: Matt and Tom both walk up the stairs of the library. Matt goes up the stairs 20 steps per minute. Tom goes up the stairs 5 steps per minute more than Matt. If Matt has reached 220 steps above the entrance, how many steps will Tom have gone up by that time?

conversations.value: Matt would have walked for 220/20=11 minutes.
  Tom would have gone up by 11*5=55 steps more.
  Tom would have gone up by 220+55=275 steps.
