conversations.value: Can you break down the solution for me for this math problem: Tim rides his bike back and forth to work for each of his 5 workdays.  His work is 20 miles away.  He also goes for a weekend bike ride of 200 miles.    If he can bike at 25 mph how much time does he spend biking a week?

conversations.value: He bikes 20*2=40 miles each day for work
  So he bikes 40*5=200 miles for work
  That means he bikes a total of 200+200=400 miles for work
  So he bikes a total of 400/25=16 hours
