conversations.value: Find a solution for this math problem: Gretchen read that you should spend 10 minutes walking for every 90 minutes you spend sitting. If Gretchen spends 6 hours working at her desk, how long will she spend walking?

conversations.value: First find the total number of minutes Gretchen spends sitting at her desk: 6 hours * 60 minutes/hour = 360 minutes
  Then divide this amount by 90 minutes to find how many walking breaks Gretchen takes: 360 minutes / 90 minutes/break = 4 breaks
  Then multiply the number of breaks by the length of each break to find how long Gretchen spends walking: 4 breaks * 10 minutes/break = 40 minutes
