conversations.value: Can you explain how to solve this math problem: Jim decides he wants to practice for a marathon coming up.  He starts off by running 5 miles every day for 30 days straight.  He then pushes himself to run 10 miles a day for the next 30 days.  Finally, as marathon day gets closer Jim runs 20 miles a day for 30 days straight.  How many miles does Jim run in total during the 90 days?
conversations.from: assistant
conversations.value: Jim runs 5 miles a day for 30 days for a total of 5*30=150 miles.
  The next month Jim runs 10 miles a day for 10*30= 300 miles.
  The last month Jim runs 20 miles a day for 20*30=600 a month.
  All together, Jim runs 150+300+600= 1050 miles in three months.
